74LVC1G157
Single 2-input multiplexer
Rev. 6 — 31 December 2012
Product data sheet
1. General description
The 74LVC1G157 is a single 2-input multiplexer which select data from two data inputs (I0
and I1) under control of a common data select input (S). The state of the common data
select input determines the particular register from which the data comes. The output (Y)
presents the selected data in the true (non-inverted) form.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these
devices as translators in mixed 3.3 V and 5 V applications.
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.
Schmitt-trigger action at all inputs makes the circuit highly tolerant to slower input rise and
fall times.
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)
CMOS low power consumption
Latch-up performance exceeds 250 mA
Direct interface with TTL levels
Inputs accept voltages up to 5 V
ESD protection:

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 SC-88 and SC-74 packages: above 87.5
C
the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 package: above 118
C
the value of P
tot
derates linearly with 7.8 mW/K.
