74LVC2G125
Dual bus buffer/line driver; 3-state
Rev. 12 — 1 December 2011
Product data sheet
1. General description
The 74LVC2G125 provides a dual non-inverting buffer/line driver with 3-state output.
The 3-state output is controlled by the output enable input (pin nOE). A HIGH-level at pin
nOE causes the output to assume a high-impedance OFF-state. Schmitt trigger action at
all inputs makes the circuit highly tolerant of slower input rise and fall times.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these
devices as translators in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing a damaging backflow current through the device
when it is powered down.
2. Features and benefits
Wide supply voltage range from 1.65 V to 5.5 V
5 V tolerant input/output for interfacing with 5 V logic
High noise immunity
Complies with JEDEC standard:
JESD8-7 (1.65 V to 1.95 V)
JESD8-5 (2.3 V to 2.7 V)
JESD8-B/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
24
mA output drive (V
CC
= 3.0 V)
CMOS low-power consumption
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
Inputs accept voltages up to 5 V
Multiple package options

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For TSSOP8 package: above 55
C
the value of P

derates linearly with 2.5 mW/K.
For VSSOP8 package: above 110
