74AHC541; 74AHCT541 Octal buffer/line driver; 3-state Rev. 4 — 14 April 2020 Product data sheet 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 S.

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 VCC • 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 3.
