SN74LV165AD

The SN74LV165AD from Texas Instruments is a parallel-load, 8-bit shift register designed for versatile operation across a 2V to 5.5V VCC range. This device shifts data towards the serial output Q H when clocked. Parallel-in access to each stage is facilitated by eight individual direct data inputs, enabled by a low level at the shift/load (SH/LD) input. The SN74LV165A series features a clock-inhibit function and a complemented serial output (Q H).

This shift register is fully specified for partial-power-down applications using I off, where the I off circuitry disables outputs to prevent damaging current backflow during power-down sequences. It supports mixed-mode voltage operation on all ports and exhibits latch-up performance exceeding 250 mA per JESD 17.

The SN74LV165AD is housed in a 16-SOIC package with a body size of 9.90 mm x 3.90 mm. It is designed for surface mount applications and operates within an extended temperature range of -40°C to 125°C. Key electrical characteristics include a maximum clock frequency of 85 MHz, with output current capabilities of 12 mA (IOL max) and -12 mA (IOH max). The supply current is a maximum of 20 µA.

This component is suitable for applications requiring an increase in the number of inputs on a microcontroller or other digital systems where serial data needs to be converted to parallel or vice versa.
