FSTD16861 - 20-Bit Bus Switch with Level Shifting

Description

The Fairchild Switch FSTD16861 provides 20-bits of highspeed CMOS TTL-compatible bus switching.

The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

Features

  • s 4Ω switch connection between two ports. s Minimal propagation delay through the switch. s Low lCC. s Zero bounce in flow-through mode. s Control inputs compatible with TTL level. s TruTranslation voltage translation from 5.0V inputs to 3.3V outputs Ordering Code: Order Number FSTD16861MTD Package Number MTD48 Package.

FSTD16861 20-Bit Bus Switch with Level Shifting May 2001 Revised May 2001 FSTD16861 20-Bit Bus Switch with Level Shifting General Description The Fairchild Switch FSTD16861 provides 20-bits of highspeed CMOS TTL-compatible bus switching. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. A diode to VCC has been integrated into the circuit to allow for level shifting between 5V inputs and 3.3V outputs. The device is organized as a 10-bit or 20-bit bus switch. When OE1 is LOW, the switch is ON and Port 1A is connected to Port 1B. When OE2 is LOW, Port 2A is connected to Port 2B. When OEX is HIGH, a high impedance state exists between the A and B Ports.
