8−Bit Bus Switch

The ON Semiconductor 74FST3245 is an 8−bit, high performance

switch. The device is CMOS TTL compatible when operating between

4 and 5.5 Volts. The device exhibits extremely low RON and adds

nearly zero propagation delay. The device adds no noise or ground

bounce to the system.

The device consists of an 8−bit switch. Port A is connected to Port B

when OE is low. If OE is high, the switch is high Z.

Features

• RON t 4 W Typical

• Less Than 0.25 ns−Max Delay Through Switch

• Nearly Zero Standby Current

• No Circuit Bounce

• Control Inputs are TTL/CMOS Compatible

• Pin−For−Pin Compatible with QS3245, FST3245, CBT3245

• All Popular Packages: QSOP−20, TSSOP−20, SOIC−20

• All Devices in Package TSSOP are Inherently Pb−Free*
