Jump to Page Section:
Overview
Description
The HD74HC540 is an inverting buffer and the HD74HC541 is a non-inverting buffer. The 3-state control gate operates as a two-input NOR such that if either G1 or G2 are high, all eight outputs are in the high-impedance state.
Features
- High-Speed Operation: tpd = 11.5 ns typ (CL = 50 pF)
- High Output Current: Fanout of 15 LSTTL Loads
- Wide Operating Voltage: VCC = 2 to 6 V
- Low Input Current: 1 µA max
- Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
