General description

The 74HC/HCT541 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/HCT541 are octal non-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 OE_n causes the outputs to assume a high impedance OFF-state.
The '541' is identical to the '540' but has non-inverting outputs.

Features

Non-inverting outputs
Output capability: bus driver
I_CC category: MSI
