Product Summary

The SN74AC373DW 8-bit latch feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The SN74AC373DW is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The SN74AC373DW is D-type transparent latches. When 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 logic levels set up at the D inputs.

Parametrics

SN74AC373DW absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input voltage range, VI: –0.5 V to VCC + 0.5 V; (3)Output voltage range, VO: –0.5 V to VCC + 0.5 V; (4)Input clamp current, IIK (VI < 0 or VI > VCC): 20 mA; (5)Output clamp current, IOK (VO < 0 or VO > VCC): 20 mA; (6)Continuous output current, IO (VO = 0 to VCC): 50 mA; (7)Continuous current through VCC or GND: 200 mA; (8)Maximum power dissipation at TA = 55°C (in still air)(see Note 2): DB package: 0.6 W, DW package: 1.6 W, N package: 1.3 W, PW package: 0.7 W; (9)Storage temperature range, Tstg: –65°C to 150°C.
