CD74HC540
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.
Key Features
- 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 pared to LSTTL Logic ICs
