TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC74LCXR164245FT

16-Bit Dual Supply Bus Transceiver with Series Resistor

The TC74LCXR164245FT 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 5-V bus and a 3.3-V

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

high-speed operation while maintaining the CMOS low power

dissipation.

It is intended for 2 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 5-V bus, the A-port with the 3.3-V or 2.5-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)

•

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

26-Ω series resistors on outputs

High-speed: t = 6.8 ns (max)

CCB

= 5.0 ± 0.5 V/V

= 3.3 ± 0.3 V, Ta = −40 to 85°C)

CCA

•

Low power dissipation: I

= 80 μA (max) (Ta = −40 to 85°C)

Symmetrical output impedance:

= ±12 mA (min)

OUTB

= ±12 mA (min)

OUTA

CCB

= 4.5V/V

= 3.0 V)

CCA

•

Power-down protection is provided on all inputs and outputs.

Allows A port and V to float simultaneously when OE is “H”

CCA

Latch-up performance: −500 mA

Package: TSSOP

Note:

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.
