1. General description
The 74AHC541; 74AHCT541 is a high-speed Si-gate CMOS device.
The 74AHC541; 74AHCT541 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
■ Balanced propagation delays
■ All inputs have a Schmitt-trigger action
■ Inputs accepts voltages higher than V
CC
■ For 74AHC541 only: operates with CMOS input levels
■ For 74AHCT541 only: operates with TTL input levels
■ ESD protection:
◆ HBM JESD22-A114E exceeds 2000 V
◆ MM JESD22-A115-A exceeds 200 V
◆ CDM JESD22-C101C exceeds 1000 V
■ Multiple package options
■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C
