74LVT16646A

3.3 V 16-bit bus transceiver; 3-state

Rev. 03 — 12 January 2005

Product data sheet

1. General description

The 74LVT16646A is a high-performance BiCMOS product designed for V_CCoperation at

3.3 V. This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible

outputs in both send and receive directions. The control function implementation

minimizes external timing requirements. The device features an output enable (OE) input

for easy cascading and a direction (DIR) input for direction control.

Data on bus A or bus B is clocked into the registers on the LOW-to-HIGH transition of the

appropriate clock (CPAB or CPBA). The select control (SAB and SBA) inputs can

multiplex stored and real-time (transparent mode data).

2. Features

■ 16-bit universal bus interface

■ 3-state buffers

■ Output capability: from +64 mA to −32 mA

■ TTL input and output switching levels

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

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

inputs

■ Live insertion and extraction permitted

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

■ Power-up reset

■ Power-up 3-state

■ Latch-up protection exceeds 500 mA per JESD78

■ ESD protection:

◆ MIL STD 883 Method 3 015: exceeds 2000 V

◆ Machine model: exceeds 200 V
