74系列逻辑芯片/TC74AC541F
TC74AC540P/F/FT Inverting, 3-State Outputs
TC74AC541P/F/FT Non-Inverting, 3-State Outputs
The TC74AC540/TC74AC541 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power
dissipation. The TC74AC540 is an inverting type, and the TC74AC541 is a non-inverting type.
