2 / 16 page 1999 Sep 27 2 Philips Semiconductors Product specification Quad buffer/line driver; 3-state 74AHC125; 74AHCT125 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. QUICK REFERENCE DATA GND = 0 V; Tamb =25 °C; tr =tf ≤ 3.0 ns. Notes 1. CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; ∑ (CL × VCC2 × fo) = sum of outputs; CL = output load capacitance in pF; VCC = supply voltage in Volts. 2. The condition is VI = GND to VCC. FUNCTION TABLE See note 1. Note 1. H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
