FSTD32450 - Fairchild Semiconductor

FSTD32450 Configurable 4-Bit to 40-Bit Bus Switch with Selectable Level Shifting (Preliminary)

The Fairchild Universal Bus Switch FSTD32450 provides 4-bit, 5-bit, 8-bit, 10-bit, 16-bit, 20-bit...40-bit of high-speed 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. The FSTD32450 is designed to allow “customer” co.

Features

s Voltage level shifting 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 Packaged in plastic Fine-Pitch Ball Grid Array (FBGA) (Preliminary) Applications Note Select pins S0, S1, S2, S3, S4 and S5 are intended to be used as static user configurable control pins. The AC performance of these pins has not been characterized or tested. Switching of these select pins during system operation may temporarily disrupt output logic states and/or enable pin controls. 40-bit c.
