Low Voltage 16-Bit Transceiver/Register with 5V Tolerant

Inputs and Outputs

General Description

Features

■ 5V tolerant inputs and outputs

The LCX16646 contains sixteen non-inverting bidirectional

registered bus transceivers with 3-STATE outputs, provid-

ing 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 16-bit operation.The DIR inputs determine the direction

of data flow through the device. The CPAB and CPBA

inputs load data into the registers on the LOW-to-HIGH

transition (see Functional Description).

■ 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)

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

The LCX16646 is designed for low voltage (2.5V or 3.3V)

V_CCapplications with capability of interfacing to a 5V signal

■ ESD performance:

Human Body Model > 2000V

Machine Model > 200V

environment.

The LCX16646 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

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

should be tied to V

through a pull-up resistor: the minimum value or the

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