CD54HC540F3A is a non-inverting eight-channel buffer and line driver with three-state outputs and the capability to drive 15 LSTTL loads produced by Harris Semiconductor.
The CD54/74HC540, CD74HCT540, CD54/74HC541, and CD54/74HCT541 are high‑speed CMOS octal buffers and line drivers with three‑state outputs. They are available in inverting (540) and non‑inverting (541) configurations and support both HC and HCT logic families.
The datasheet lists pinouts, truth tables, absolute maximum ratings, DC electrical specifications, switching performance, and mechanical dimensions. Key performance figures include a typical propagation delay of 9 ns at 5 V, fan‑out of up to 15 LSTTL loads, and operation over a temperature range of –55 °C to 125 °C.
| Typical Propagation Delay | 9 ns at VCC = 5 V |
|---|---|
| Standard Output Fan‑out | 10 LSTTL loads |
The typical propagation delay is 9 ns when powered at 5 V.
A standard output can drive up to 10 LSTTL loads.
