1. General description

The 74VHC541; 74VHCT541 are high-speed Si-gate CMOS devices.

The 74VHC541; 74VHCT541 are octal non-inverting buffer/line drivers with 3-state bus

compatible outputs.

The 3-state outputs are controlled by the output enable inputs OE0 and OE1.

A HIGH on OEn causes the outputs to assume a high-impedance OFF-state.

2. Features

n Balanced propagation delays

n All inputs have a Schmitt-trigger action

n Inputs accepts voltages higher than V

n The 74VHC541 operates with CMOS input level

n The 74VHCT541 operates with TTL input level

n ESD protection:

u HBM JESD22-A114E exceeds 2000 V

u MM JESD22-A115-A exceeds 200 V

u CDM JESD22-C101C exceeds 1000 V

n Multiple package options

n Speciﬁed from −40 °C to +85 °C and from −40 °C to +125 °C
