74LVT244B; 74LVTH244B

3.3 V octal buffer/line driver; 3-state

Rev. 03 — 3 March 2006

Product data sheet

1. General description

The 74LVT244B; 74LVTH244B is a high-performance BiCMOS product designed for V

operation at 3.3 V.

This device is an octal buffer that is ideal for driving bus lines. The device features two

output enable inputs (1OE and 2OE), each controlling four of the 3-state outputs.

2. Features

Octal bus interface

3-state buffers

Speed upgrade of 74LVT244A

Output capability: +64 mA and

−32

TTL input and output switching levels

Input and output interface capability to systems at 5 V supply

Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs

Power-up 3-state

Live insertion and extraction permitted

No bus current loading when output is tied to 5 V bus

Latch-up protection:

JESD78: exceeds 500 mA

ESD protection:

HBM EIA/JESD22-A114-C exceeds 2000 V

MM EIA/JESD22-A115-A 200 V
