1. General description
The 74LVC126A consists of four non-inverting buffers/line drivers with 3-state outputs,
which are controlled by the output enable inp ut (nOE). A LOW at nOE causes the ou tput s
to assume a high-impedance OFF-state.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs.
2. Features and benefits
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Specified from 40 C to +85 C and 40 C to +125 C

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
