74HCT373D,652

Latches Overview

The Nexperia 74HCT373D,652 is an octal D-type transparent latch with 3-state outputs housed in a SO20 (SOT163-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level inputs, non-inverting outputs, and a common output enable input. Static characteristics include a maximum supply current of 80 μA at -40 °C to 85 °C. Dynamic performance specifies a typical propagation delay of 30 ns at 4.5 V.
