74LCX32646

Low Voltage 32-Bit Transceiver/Register

with 5V Tolerant Inputs and Outputs (Preliminary)

General Description

Features

■ 5V tolerant inputs and outputs

The LCX32646 contains thirty-two non-inverting bidirec-

tional registered bus transceivers with 3-STATE outputs,

providing multiplexed transmission of data directly from the

input bus or from the internal storage registers. Each byte

has separate control inputs which can be shorted together

for full 32-bit operation.The DIR_ninputs determine the

■ 2.3V–3.6V V_CCspecifications provided

■ 5.2 ns t_PDmax (V_CC= 3.3V), 20 µA I_CCmax

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ ±24 mA Output Drive (V_CC= 3.0V)

direction of data flow through the device. The CPAB_nand

CPBA_ninputs load data into the registers on the LOW-to-

HIGH transition (see Functional Description).

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

The LCX32646 is designed for low voltage (2.5V or 3.3V)

■ ESD performance:

Human Body Model > 2000V

Machine Model > 200V

V_CCapplications with capability of interfacing to a 5V signal

environment.

The LCX32646 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

■ Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)

(Preliminary)

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.
