74LVC2G126
Dual bus buffer/line driver; 3-state
Rev. 12 — 8 April 2013
Product data sheet
1. General description
The 74LVC2G126 is a dual non-inverting buffer/line driver with 3-state outputs. Each
3-state output is controlled by an output enable input (pin nOE). A LOW-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 the
74LVC2G126 as a translator in a mixed 3.3 V and 5 V environment.
It is fully specified for partial power-down applications using IOFF. The IOFF 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 (VCC = 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
Specified from 40 C to +85 C and 40 C to +125 C

[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3] For TSSOP8 packages: above 55 C the value of Ptot derates linearly at 2.5 mW/K.
For VSSOP8 packages: above 110 C the value of Ptot derates linearly at 8.0 mW/K.
For XSON8 and XQFN8 packages: above 118 C the value of Ptot derates linearly with 7.8 mW/K.
