Product Summary

The SN74HC373N is an 8-bit latch. It features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The SN74HC373N is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

Parametrics

SN74HC373N absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (5)Continuous current through VCC or GND: ±70 mA; (6)Package thermal impedance, θJA: 70℃/W; (7)Storage temperature range, Tstg: -65 to 150℃.
