74HC125-Q100; 74HCT125-Q100
Quad buffer/line driver; 3-state
Rev. 2 — 19 January 2015
Product data sheet
1. General description
The 74HC125-Q100; 74HCT125-Q100 is a quad buffer/line driver with 3-state outputs
controlled by the output enable inputs (nOE). A HIGH on nOE causes the outputs to
assume a high impedance OFF-state. Inputs include clamp diodes which enable the use
of current limiting resistors to interface inputs to voltages in excess of VCC.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
Specified from 40 C to +85 C and from 40 C to +125 C
Complies with JEDEC standard no. 7A
Input levels:
The 74HC125-Q100: CMOS levels
The 74HCT125-Q100: TTL levels
ESD protection:
MIL-STD-883, method 3015 exceeds 2000 V
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 )

CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
(CL VCC2 fo) = sum of outputs.
