74AHC541; 74AHCT541 Octal buffer/line driver; 3-state Rev. 03 — 12 November 2007 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 inputsOE0 andOE1. A HIGH onOEn causes the outputs to assume a high-impedance OFF-state. 2. Features n Balanced propagation delays n All inputs have a Schmitt-trigger action n Inputs accepts voltages higher thanV CC n For 74AHC541 only: operates with CMOS input levels n For 74AHCT541 only: operates with TTL input levels n ESD protection: u HBM JESD22-A114E exceeds 2000V u MM JESD22-A115-A exceeds 200V u CDM JESD22-C101C exceeds 1000V n Multiple package options n Specified from-40 (cid:176)C to +85 (cid:176)C and from -40 (cid:176)C to +125 (cid:176)C 3.
