74LVC1G126
Bus buffer/line driver; 3-state
Rev. 13 — 2 December 2016
Product data sheet
1. General description
The 74LVC1G126 provides one non-inverting buffer/line driver with 3-state output. The
3-state output is controlled by the output enable input (OE). A LOW-level at pin OE
causes the output to assume a high-impedance OFF-state.
The input can be driven from either 3.3 V or 5 V devices. This feature allows the use of
this device 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 the 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
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)
JESD8B/JESD36 (2.7 V to 3.6 V)
24
mA output drive (V
CC
= 3.0 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CMOS low power consumption
Inputs accept voltages up to 5 V
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
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 TSSOP5 and SC-74A packages: above 87.5
C
the value of P

derates linearly with 4.0 mW/K.
For XSON6 and X2SON5 package: above 118
