74HC373N,652

Latches Overview

The NXP USA Inc. 74HC373N,652 is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It features a latch enable (LE) input and an output enable (OE) input. The device operates within a supply voltage range of 2.0 V to 6.0 V. Propagation delay from data inputs to outputs is typically 15 ns at 4.5 V and 12 ns at 5 V with 15 pF load capacitance. Supply current is typically 8 μA at 6.0 V. The component is housed in a 20-pin DIP package.

Latches Feature Summary

• Octal D-type transparent latch architecture with independent data inputs
• Three-state non-inverting outputs suitable for bus-oriented applications
• Common three-state output enable input for high-impedance control
