SN74LXCH1T45_V01規(guī)格書詳情

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.
