74AC374MTR

Overview

The STMicroelectronics 74AC374MTR is an octal D-type flip-flop featuring three-state outputs, manufactured in a 20-SOIC package. It operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 270 MHz at 5V. The device exhibits a typical propagation delay of 9.5ns at 5V with 50pF load, ensuring symmetrical delays. Static current consumption is limited to 4µA maximum. Output drive capability provides 24mA for both high and low states, while input capacitance is specified at 4pF. The component functions as a positive-edge triggered latch with non-inverted outputs.
