74LCXH16245

Low Voltage 16-Bit Bidirectional Transceiver

with Bushold

General Description

Features

The LCXH16245 contains sixteen non-inverting bidirec-

tional buffers with 3-STATE outputs and is intended for bus

oriented applications. The device is designed for low volt-

age (2.5V or 3.3V) V_CCapplications with capability of inter-

■ 2.3V–3.6V V_CCspecifications provided

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

■ Power-down high impedance outputs

■ Bushold on inputs eliminates the need for external

pull-up/pull-down resistors

facing to a 5V signal environment. The device is byte

controlled. Each byte has separate control inputs which

could be shorted together for full 16-bit operation. The T/R

inputs determine the direction of data flow through the

device. The OE inputs disable both the A and B Ports by

placing them in a high impedance state.

■ ±24 mA output drive (V_CC= 3.0V)

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance conforms to the requirements of

JESD78

The LCXH16245 data inputs include active bushold cir-

cuitry, eliminating the need for external pull-up resistors to

hold unused or floating data inputs at a valid logic level.

■ ESD performance:

Human body model > 2000V

Machine model > 200V

The LCXH16245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

■ Also packaged in plastic Fine-Pitch Ball Grid Array

(FBGA)
