Description
The shift register is clocked using a clock input pin (CP), and the data is shifted on the positive edge of the clock signal. An asynchronous clear input (CLR) is provided to reset all outputs to low, ensuring that the register can be quickly initialized. The SN74LS164N is packaged in a standard Dual In-line Package (DIP), making it easy to integrate into various projects. It is widely used in applications like digital counters, LED displays, and data conversion systems due to its reliability and ease of use.
Equivalent
1. CD4094 - CMOS 8-bit shift register with latch
2. 74HC164 - High-speed CMOS version of the 74LS164
3. NTE74LS164 - NTE's equivalent for the SN74LS164
4. MC14094 - Motorola's equivalent 8-bit shift register
5. HEF4094 - Philips' equivalent 8-bit shift register
These alternatives offer similar functionalities, though electrical characteristics may vary. Always check the datasheet for compatibility.
Features
1. 8-Bit Shift Register: Capable of shifting data in a serial format and outputting in parallel.
2. High-Speed Operation: Suitable for high-frequency applications.
3. Serial Data Input: Features A and B inputs for serial data entry.
4. Clear Function: Has an asynchronous reset which clears the register.
5. TTL Compatible: Designed to work with TTL logic levels.
6. Wide Operating Voltage Range: Typically operates efficiently within a 4.75V to 5.25V range.
7. Cascading Capability: Allows multiple SN74LS164N devices to be connected for longer data sequences.
8. No Clock Skew: Parallel outputs change simultaneously with the clock.
9. Package: Usually comes in a 14-pin DIP (Dual In-line Package).
These features make the SN74LS164N suitable for use in data storage, data transfer, and digital signal processing applications.
Pinout
