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 .
• ’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 opera.
