INTEGRATED CIRCUITS DATA SHEET 74AHC125; 74AHCT125 Quad buffer/line driver; 3-state Product specification Supersedes data of 1999 Jan 11 File under Integrated Circuits, IC06 1999 Sep 27 Philips Semiconductors Product specification Quad buffer/line driver; 3-state FEATURES ESD protection: HBM EIA/JESD22-A114-A exceeds 2000 V MM EIA/JESD22-A115-A exceeds 200 V CDM EIA/JESD22-C101 exceeds 1000 V Balanced propagation delays All inputs have Schmitt-trigger actions Inputs accepts voltages higher than VCC For AHC only: operates with CMOS input levels For AHCT only: operates with TTL input levels Specified from −40 to +85 and +125 °C. DESCRIPTION The 74AHC/AHCT125 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC/AHCT125 are 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 n causes the outputs to assume a HIGH-impedance OFF-state. The ‘125’ is identical to the ‘126’ but has active LOW enable inputs. 74AHC125; 74AHCT125 QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf ≤ 3.0 ns.
