74LVC1G19
1-of-2 decoder/demultiplexer
Rev. 6 — 6 December 2011
Product data sheet
1. General description
The 74LVC1G19 is a 1-of-2 decoder/demultiplexer with a common output enable. This
device buffers the data on input A and passes it to the outputs 1Y (true) and 2Y
(complement) when the enable (E) input signal is LOW.
Inputs can be driven from either 3.3 V or 5 V devices. These features allow the use of
these devices 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
5 V tolerant inputs 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)
JESD8B/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
Specified from
40 C
to +85
C
and
40 C
to +125
C.

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