1 Features
? Fully configurable dual-rail design allows each port
to operate from 1.1 V to 5.5 V
? Robust, glitch-free power supply sequencing
? Up to 420-Mbps support for 3.3 V to 5.0 V
? Bus hold on data inputs eliminates the need for
external pull-up and pull-down resistors
? Schmitt-trigger control inputs allow for slow or
noisy inputs
? Control inputs with integrated static pull-down
resistors allow for floating control inputs
? High drive strength (up to 32 mA at 5 V)
? Low power consumption
– 3-μA maximum (25°C)
– 6-μA maximum (–40°C to 125°C)
? VCC isolation and VCC disconnect feature
– If either VCC supply is < 100 mV all I/O's
become high-impedance
– Ioff-float supports VCC disconnect operation
? Ioff supports partial-power-down mode operation
? Compatible with LVC family level shifters
? Control logic (DIR) are referenced to VCCA
? Operating temperature from –40°C to +125°C
? Latch-up performance exceeds 100 mA per JESD
78, class II
? ESD protection exceeds JESD 22
– 4000-V human-body model
– 1000-V charged-device model
2 Applications
? Eliminate slow or noisy input signals
? Driving indicator LEDs or buzzers
? Debouncing a mechanical switch
? General purpose I/O level shifting
3 Description
The SN74LXCH1T45 is an 1-bit, dual-supply
noninverting bidirectional voltage level translation
device with bus-hold circuitry. The I/O pin A and
control pin (DIR) are referenced to VCCA logic levels,
and the I/O pin B is referenced to VCCB logic levels.
The A pin is able to accept I/O voltages ranging
from 1.1 V to 5.5 V, while the B port can accept I/O
voltages from 1.1 V to 5.5 V. A high on DIR allows
data transmission from A to B and a low on DIR
allows data transmission from B to A. See Device
Functional Modes for a summary of the operation of
the control logic.
