SN74HC377DWR

Flip Flops Overview

The SN74HC377DWR is an octal D-type flip-flop with clock enable, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features non-inverting outputs. The device utilizes a 20-SOIC surface-mount package and supports a maximum clock frequency of 64 MHz. Propagation delay is specified at 27ns under standard test conditions (6V, 50pF load). It maintains a static current consumption of 8 µA and provides output drive capabilities of 5.2mA for both high and low states. The component functions reliably across an operating temperature range of -40°C to +85°C.
