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
nBalanced propagation delays
nAll inputs have a Schmitt-trigger action
nInputs accepts voltages higher than VCC
nThe 74VHC541 operates with CMOS input level
nThe 74VHCT541 operates with TTL input level
nESD protection:
uHBM JESD22-A114E exceeds 2000 V
uMM JESD22-A115-A exceeds 200 V
uCDM JESD22-C101C exceeds 1000 V
nMultiple package options
nSpecified from 40 °C to +85 °C and from 40 °C to +125 °C
