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 � 4 � 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*
