The 74HC/HCT540 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT540 are octal inverting buffer/line drivers with 3-state outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2.
A HIGH on OEn causes the outputs to assume a high impedance OFF-state.
The “540” is identical to the “541” but has inverting outputs.

· Inverting outputs
· Output capability: bus driver
