74AHC125; 74AHCT125 Quad buffer/line driver; 3-state Rev. 04 — 11 January 2008 Product data sheet 1. General description The 74AHC125; 74AHCT125 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard JESD7-A. The 74AHC125; 74AHCT125 provides four non-inverting buffer/line drivers with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input (nOE). A HIGH at nOE causes the outputs to assume a high-impedance OFF-state. The 74AHC125; 74AHCT125 is identical to the 74AHC126; 74AHCT126 but has active LOW enable inputs. 2. Features ■ ■ ■ ■ ■ ■ Balanced propagation delays All inputs have a Schmitt-trigger action Inputs accepts voltages higher than VCC For 74AHC125 only: operates with CMOS input levels For 74AHCT125 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.
