74HC126-Q100; 74HCT126-Q100
Quad buffer/line driver; 3-state
Rev. 1 — 20 March 2013
Product data sheet
1. General description
The 74HC126-Q100; 74HCT126-Q100 is a quad buffer/line driver with 3-state outputs
controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to
assume a high impedance OFF-state. Inputs include clamp diodes. This enables the use
of current limiting resistors to interface inputs to voltages in excess of V
CC
.
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
Inverting outputs
Complies with JEDEC standard no. 7A
Input levels:
For 74HC126-Q100: CMOS level
For 74HCT126-Q100: TTL level
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
)
