TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74LCXR163245FT

16-Bit Dual Supply Bus Transceiver with Series Resistor

The TC74LCXR163245FT is a dual supply, advanced high-speed

CMOS 16-bit dual supply voltage interface bus transceiver

fabricated with silicon gate CMOS technology.

Designed for use as an interface between a 3.3-V or a 2.5-V bus

and a 5-V bus in mixed 3.3-V or 2.5-V/5-V supply systems, it

achieves high-speed operation while maintaining the CMOS low

power dissipation.

It is intended for two-way asynchronous communication between

data busses. The direction of data transmission is determined by the

level of the DIR input. The enable input ( OE ) can be used to disable

the device so that the buses are effectively isolated.

The B-port interfaces with the 3.3 V or 2.5 V bus, the A-port with

the 5 V bus.

Weight: 0.25 g (typ.)

The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor.

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features (Note 1) (Note 2)

•

Bidirectional interface between 3.3 V or 2.5 V buses and 5 V buses

26-Ω series resistors on outputs

High-speed operation: t = 8.5 ns (max)

CCB

= 3.3 ± 0.3 V/V

= 5 ± 0.5 V, Ta = −40 to 85°C)

CCA

•

Low-voltage operation: I

= 80 μA (max) (Ta = −40 to 85°C)

Symmetrical output impedance: I

= ±12 mA (min)

OUTB

= ±12 mA (min)

OUTA

CCB

= 3.0 V/V

= 4.5 V)

CCA

•

Power-down protection provided on all inputs and outputs

Allows A port and V to float simultaneously in high state at OE pin

CCA

Latch-up performance: −500 mA

ESD performance: Machine model > ±200 V (Note 2)

Package: TSSOP

Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.

All floating (high impedance) bus pins must have their input fixed by means of pull-up or pull-down resistors.

Note 2: This device is electrostatic sensitivity (human body model > 1 kV).

Please handle with caution.
