Product overview

SN74LV244ADBRE4 at a glance

SN74LV244ADBRE4 is an active-production, eight-channel noninverting buffer and line driver for 2 V to 5.5 V systems. It divides the channels into two four-bit groups with separate active-low output-enable controls and presents high-impedance outputs when disabled. The exact DBRE4 orderable code uses a 20-pin SSOP package and large tape-and-reel carrier, with partial-power-down support and over-voltage-tolerant inputs for mixed-voltage interfaces.

Key features

Verified device capabilities

Two independently enabled four-bit banks provide buffering and bus isolation in one device.
Operation from 2 V to 5.5 V supports common low-voltage and 5 V logic rails.
Ioff circuitry supports powered-down isolation and helps prevent back-drive current.
TI specifies a maximum propagation delay of 6.5 ns at a 5 V supply.

Applications

Where the device is used

Three-state outputs let two groups connect to or isolate shared digital buses.
The device is intended to improve performance and density in memory-address driver paths.
Balanced multi-channel outputs can buffer moderate-speed digital clocks within datasheet loading limits.
Over-voltage-tolerant inputs and partial-power-down behavior help interface logic domains with coordinated output-enable control.

Technical and ordering FAQ

Questions buyers ask about SN74LV244ADBRE4

Answers distinguish the IC itself from assembled modules and keep absolute limits separate from normal operating conditions.

How many channels are in SN74LV244ADBRE4?

It contains eight noninverting buffer channels arranged as two independently enabled four-bit banks.

What package is used by the DBRE4 code?

The exact orderable code uses TI's 20-pin DB SSOP package on a large tape-and-reel carrier.

Can the outputs be disconnected from a bus?

Yes. Each four-bit bank has a separate output-enable input, and disabled outputs enter the high-impedance state.
