74LCX646

Low Voltage Octal Transceiver/Register

with 5V Tolerant Inputs and Outputs

General Description

Features

■ 5V tolerant inputs and outputs

The LCX646 consists of registered bus transceiver circuits,

D-type flip-flops, and control circuitry providing multiplexed

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 pin (CPAB or CPBA) (see

Functional Description).

■ 2.3V − 3.6V V_CCspecifications provided

■ 7.0 ns t_PDmax (V_CC= 3.3V), 10 µA I_CCmax

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ ±24 mA output drive (V_CC= 3.0V)

The LCX646 is designed for low voltage (2.5V or 3.3V) V_CC

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ ESD performance:

applications with capability of interfacing to a 5V signal

environment.

The LCX646 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

Human body model > 2000V

Machine model > 200V

Note 1: To ensure the high-impedance state during power up or down, OE

should be tied to V_CCthrough a pull-up resistor: the minimum value or the

resistor is determined by the current-sourcing capability of the driver.
