SN54LS165AJ Description

Short technical summary and product information.

The SN54LS165AJ is an 8-bit serial shift register from Texas Instruments that shifts data from QA toward QH when clocked. Parallel-in access to each stage is provided by eight direct data inputs enabled by a low level at the shift/load (SH/LD\) input. The device also features gated clock (CLK) inputs and complementary outputs from the eighth bit, and all inputs are diode-clamped to minimize transmission-line effects.

 

Key specifications include a supply voltage range of 4.5V to 5.5V, operating temperature range of -55°C to 125°C, and a through-hole CDIP package with 16 pins. The device complements the earlier SN54165 and SN74165 devices, which are obsolete.

 

This shift register is designed for parallel-to-serial data conversion and can be used in applications requiring register expansion or serial data transmission. The package quantity is 25 pieces per tube, and the lead finish is SnPb (non-RoHS).
