74HC125 datasheet, circuit
74HC125; 74HCT125
Quad buffer/line driver; 3-state
Rev. 6 — 1 December 2015
Product data sheet
1. General description
The 74HC125; 74HCT125 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. This enables the use of current
limiting resistors to interface inputs to voltages in excess of VCC.
2. Features and benefits
Complies with JEDEC standard no. 7A
Input levels:
The 74HC125: CMOS levels
The 74HCT125: TTL levels
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
