Product Overview
The SN74HC595DR is a Texas Instruments 8-bit shift register in the Signal_Chain category. Its logic function is an 8-bit serial-in, parallel-out shift register combined with an 8-bit D-type storage register. Storage register outputs are parallel 3-state outputs, allowing the QA-QH outputs to be enabled, disabled, or driven according to the register state.
Recommended operation covers a 2 V to 6 V supply range with input and output voltage ranges from 0 V to VCC. For SN74HC595 operation, the free-air temperature range is -40 °C to 85 °C. Output drive is specified as ±6 mA at VCC = 5 V, with feature values including 13 ns typical propagation delay, 1 µA maximum input current, and 80 µA maximum low-power consumption.
The SN74HC595DR package is SOIC-16, Texas Instruments D package, with a 9.90 mm × 3.90 mm body size. Thermal data lists 73 °C/W junction-to-ambient thermal resistance for SN74HC595D SOIC-16. Timing specifications include 25 MHz maximum clock frequency at 4.5 V, 29 MHz at 6 V, and 20 ns minimum SRCLK or RCLK pulse duration at 4.5 V.
