Construct and test this circuit. Latches The 74LS is an eight-bit transparent latch, while the 74LS is an eight-bit edge-triggered latch. The Soviet integrated circuit designation is different from the Western series:. Before July the two letters from the functional description were inserted after the first digit of the series.

Since the s, new product families have been released to replace the original series. Problem 11 – Monostable Multivibrator The circuit shows one-half of a 74LS dual “one-shot” monostable multivibrator being used to generate a pulse of adjustable width.

Retrieved 8 June Ordinarily this is a Bad Thing because outputs could drive into each other, but for open collector it’s fine: The eight-bit buffers 74LS and 74LS are functionally equivalent to the widely used 74LS and 74LS; however the ‘ and ‘ have a more confusing pin-out to trip the unwary student.

Although the series was the first de facto industry standard TTL logic family i. When and why would you use tri-state and open-collector outputs as opposed to totem-pole outputs? Along the way I’ll also cover some additional chip characteristics that can be useful in complex designs. Around the production of standard logic ceased in all Eastern European countries except the Soviet Union and later Russia and Belarus. While designed as a family of digital logic, some TTL chips were used in analogue circuits, such as Schmitt triggers [ citation needed ].


Texas Instruments also manufactured radiation-hardened devices with the prefix RSNand the company offered beam-lead bare dies for integration into hybrid circuits with a BL prefix designation. Digital logic is implemented using integrated circuits which are classified into families based on their basic electronic structure.

The 74LS family of ICs is a lower-power version of the 74S family, with slightly higher speed but lower power dissipation than the original 74 family; it became the most popular variant once it was widely available. Two important factors in the consideration of each logic family are speed and power consumption. An open-collector output has current sinking capabilities, that is, it can present a logic-LO output.

Some manufacturers, such as Mullard and Siemens, had pin-compatible TTL parts, but with a completely different numbering scheme; however, data sheets identified the compatible number as an aid to recognition. This is called the high impedance or Hi-Z state.

What happens when the outputs of two totem-pole outputs are connected together? Retrieved 11 November Since open collector is often used where “0” is 74z00 active state, this is also called a “wired-OR” connection, referring to an active-low OR function.

The “Recommended Operating Conditions” table will define the conditions for actual device operation.

These can datasgeet used in cases where the final output of a logic function only needs to sink current; a later section will give examples where this can be used. The tri-state bus driver has an enable input G.

Because tri-state buffers have many applications in microprocessor circuits, there are several useful chips available which are designed to dattasheet on eight data signals bits at one time. There are six of these on a single chip.

Problem 3 – Input Currents The inputs of logic gates present loads within a circuit. The 74LS00 family We’ve already spent time looking at the TTL logic family, even though I only introduced the first part in the family. A number of different technologies were available from the Soviet Union, [28] [33] [34] [35] [29] Czechoslovakia, [36] [31] Poland, [29] [31] and East Germany.

It was jokingly referred to in the Eastern Bloc electronics industry as the “elephant-dung packaging”, due to its appearance. Open-Collector Output Figure 6. From Wikipedia, the free encyclopedia. Regardless of the IC’s complexity or how it is created, basic knowledge of gates and flip-flops is still essential.
