74AUP1T34
Low-power dual supply translating buffer
Rev. 5 — 4 September 2013
Product data sheet
1. General description
The 74AUP1T34 provides a single buffer with two separate supply voltages. Input A is
designed to track V
CC(A)
. Output Y is designed to track V
CC(Y)
. Both, V
CC(A)
and V
CC(Y)
accepts any supply voltage from 1.1 V to 3.6 V. This feature allows universal low voltage
interfacing between any of the 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V voltage nodes.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall
times across the entire V
CC
range from 1.1 V to 3.6 V. This device ensures a very low
static and dynamic power consumption across the entire V
CC
range from 1.1 V to 3.6 V.
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 1.1 V to 3.6 V
High noise immunity
Complies with JEDEC standards:
JESD8-7 (1.2 V to 1.95 V)
JESD8-5 (1.8 V to 2.7 V)
JESD8-B (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F Class 3A exceeds 5000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Wide supply voltage range:
V
CC(A)
: 1.1 V to 3.6 V
V
CC(Y)
: 1.1 V to 3.6 V
Low static power consumption; I
CC
= 0.9
A
(maximum)
Each port operates over the full 1.1 V to 3.6 V power supply range
Latch-up performance exceeds 100 mA per JESD 78 Class II
Inputs accept voltages up to 3.6 V
Low noise overshoot and undershoot < 10 % of V
CC
