HD74HCT540/HD74HCT541
Octal Buffers/Line Drivers (with 3-state outputs)
Description
The HD74HCT540 is an inverting buffer and the HD74HCT541 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
• LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility
• High Speed Operation: tpd (A to Y) = 12 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 4.5 to 5.5 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
