3.3 V 16-bit buffer/driver; 3-state

Rev. 05 — 21 March 2006

Product data sheet

1. General description

The 74LVT16244B; 74LVTH16244B is a high-performance BiCMOS product designed for

V_CCoperation at 3.3 V.

This device is a 16-bit buffer and line driver featuring non-inverting 3-state bus outputs.

The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.

2. Features

I 16-bit bus interface

I 3-state buffers

I Output capability: +64 mA and −32 mA

I TTL input and output switching levels

I Input and output interface capability to systems at 5 V supply

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

I Power-up 3-state

I Live insertion and extraction permitted

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

I Latch-up protection:

N JESD78: exceeds 500 mA

I ESD protection:

N MIL STD 833 method 3015: exceeds 2000 V

N Machine model: exceeds 200 V
