Texas Instruments SN74AC165/SN74AC165-Q1 8-Bit Shift Registers

Texas Instruments SN74AC165/SN74AC165-Q1 8-Bit Parallel Input Shift Registers have a serial data input (SER), standard and inverted serial outputs (QH, /QH), and clock inhibit input (CLK INH). A parallel-in access to each stage is provided by eight individual direct data (A-H) inputs enabled by a low level at the shift/load (SH//LD) input. These devices also feature a complementary serial (/QH) output and a clock-inhibit (CLK INH) function. The Texas Instruments SN74AC165-Q1 devices are AEC-Q100 qualified for automotive applications.

Features

  • Wide operating range of 1.5V to 6V
  • Inputs accept voltages up to 6V
  • Continuous ±24mA output drive at 5V
  • Supports up to ±75mA output drive at 5V in short bursts
  • Drives 50Ω transmission lines
  • Maximum tpd of 10.1ns at 5V, 50pF load

Applications

  • Increase the number of inputs on a microcontroller
  • Read in board revision
