Octal Buffers/Line Drivers (with 3-state outputs)
REJ03D0628-0200 (Previous ADE-205-508) Rev.2.00 Mar 30, 2006
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 A max * Low Quiescent Supply Current: ICC (static) = 4 A max (Ta = 25C) * Ordering Information
