74VHC541; 74VHCT541
Octal buffer/line driver; 3-state
Rev. 01 — 12 August 2009
Product data sheet
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
I Balanced propagation delays
I All inputs have a Schmitt-trigger action
I Inputs accepts voltages higher than VCC
I The 74VHC541 operates with CMOS input level
I The 74VHCT541 operates with TTL input level
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
N CDM JESD22-C101C exceeds 1000 V
I Multiple package options
I Specified from −40 °C to +85 °C and from −40 °C to +125 °C
