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
s s s s s s 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: x HBM JESD22-A114E exceeds 2000 V x MM JESD22-A115-A exceeds 200 V x CDM JESD22-C101C exceeds 1000 V s Multiple package options s Specified from -40 C to +85 C and from -40 C to +125 C

Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz, fo = output frequency in MHz CL = output load capacitance in pF VCC = supply voltage in Volts N = number of inputs switching (CL x VCC2 x fo) = sum of the outputs.
