74LCX32652

Low Voltage Transceiver/Register

with 5V Tolerant Inputs and Outputs (Preliminary)

General Description

Features

■ 5V tolerant inputs and outputs

The LCX32652 contains thirty-two non-inverting bidirec-

tional bus transceivers with 3-STATE outputs providing

multiplexed transmission of data directly from the input bus

or from the internal registers. Data on the A or B bus will be

clocked into the registers as the appropriate clock pin goes

to the HIGH logic level. Each byte has separate control

inputs which can be shorted together for full 32-bit opera-

tion. Output Enable pins (OEAB_n, OEBA_n) are provided to

■ 2.3V–3.6V V_CCspecifications provided

■ 5.7 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)

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ ESD performance:

control the transceiver function (see Functional Descrip-

tion).

The LCX32652 is designed for low-voltage (2.5V or 3.3V)

V_CCapplications with capability of interfacing to a 5V signal

Human body model > 2000V

environment.

Machine model > 200V

The LCX32652 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_CCand OE tied to GND through a resistor: the minimum

value or the resistor is determined by the current-sourcing capability of the

driver.
