74LVTH646

Low Voltage Octal Transceiver/Register

with 3-STATE Outputs

General Description

Features

■ Input and output interface capability to systems at

The LVTH646 consists of registered bus transceiver cir-

cuits, D-type flip-flops, and control circuitry providing multi-

plexed transmission of data directly from the input bus or

from the internal storage registers. Data on the A or B bus

will be loaded into the respective registers on the LOW-to-

HIGH transition of the appropriate clock pin (CPAB or

CPBA). (See Functional Description)

5V V_CC

■ Bushold data inputs eliminate the need for external

pull-up resistors to hold unused inputs

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free

bus loading

The LVTH646 data inputs include bushold, eliminating the

need for external pull-up resistors to hold unused inputs.

■ Outputs source/sink −32 mA/+64 mA

■ Functionally compatible with the 74 series 646

■ Latch-up performance exceeds 500 mA

■ ESD performance:

The bus transceivers are designed for low-voltage (3.3V)

V_CCapplications, but with the capability to provide a TTL

interface to a 5V environment. The LVTH646 is fabricated

with an advanced BiCMOS technology to achieve high

speed operation similar to 5V ABT while maintaining low

power dissipation.
