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 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 3.
