Overview
CD54HC540, CD74HC540, CD54HC541, CD74HC541, CD74HCT540, CD54HCT541, CD74HCT541 SCHS189E – JANUARY 1998 – REVISED OCTOBER 2022 CDx4HC(T)541 High-Speed CMOS Logic Octal Buffer and Line Drivers Three-State 1 Features • ’HC540, CD74HCT540: inverting • ’HC541, ’HCT541: non-inverting • Buffered inputs • Three-state outputs • Bus line driving capability • Typical propagation delay = 9 ns at VCC = 5 V, CL = 15 pF, TA = 25℃ • Fanout (over temperature range) – Standard outputs: 10 LSTTL loads – Bus driver outputs: 15 LSTTL loads • Wide operating temperature range: –55℃ to 125℃ • Balanced propagation delay and transition times • Significant power reduction compared to LSTTL Logic ICs • HC types – 2 V to 6 V operation – High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5 V • HCT types – 4.
5 V to 5.
5 V operation – Direct LSTTL input logic compatibility, VIL = 0.
8 V (max), VIH = 2 V (min) – CMOS input compatibility, II ≤ 1 μA at VOL, VOH 2 Description The ’HC540 and CD74HCT540 are Inverting Octal Buffers and Line Drivers with Three-State Outputs and the capability to drive 15 LSTTL loads.
The ’HC541 and ’HCT541 are Noninverting Octal Buffers and Line Drivers with Three-State Outputs that can drive 15 LSTTL loads.
The Output Enables (OE1) and (OE2) control the Three-State Outputs.
If either OE1 or OE2 is HIGH the outputs will be in the high impedance state.
For data output OE1 and OE2 both must be LOW.
