74VHC541; 74VHCT541
Octal buffer/line driver; 3-state
Rev. 2 — 3 September 2020
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 and benefits
•
•
•
•
•
•
Balanced propagation delays
All inputs have a Schmitt-trigger action
Inputs accepts voltages higher than V
CC
The 74VHC541 operates with CMOS input level
The 74VHCT541 operates with TTL input level
ESD protection:
•
HBM JESD22-A114E exceeds 2000 V
•
MM JESD22-A115-A exceeds 200 V
•
CDM JESD22-C101C exceeds 1000 V
