NC7WBD3125

TinyLogic UHS 2-Bit Low Power Bus Switch

with Level Shifting

General Description

Features

■ Space saving US8 surface mount package

The NC7WBD3125 is a 2-bit ultra high-speed CMOS FET

bus switch with enhanced level shifting circuitry and with

TTL-compatible active LOW control inputs. The low On

Resistance of the switch allows inputs to be connected to

outputs with minimal propagation delay and without gener-

ating additional ground bounce noise. The device is orga-

nized as a 2-bit switch with independent bus enable (OE)

controls. When OE is LOW, the switch is ON and Port A is

connected to Port B. When OE is HIGH, the switch is

OPEN and a high-impedance state exists between the two

ports. Reduced voltage drive to the gate of the FET switch

permits nominal level shifting of 5V to 3V through the

switch. Control inputs tolerate voltages up to 5.5V indepen-

■ MicroPak leadless package

■ Typical 3Ω switch resistance at 5.0V V_CC, V_IN= 0V

■ Level shift facilitates 5V to 3.3V interfacing

■ Minimal propagation delay through the switch

■ Power down high impedance input/output

■ Zero bounce in flow through mode

■ TTL compatible active LOW control inputs

■ Control inputs are overvoltage tolerant

■ Bus switch replacement for x125 logic part
