FSTU3384 - 10-Bit Bus Switch with -2V Undershoot Hardened Circuit (UHC) Protection

Datasheet Summary

Description

The Fairchild Switch FSTU3384 provides 10 bits of highspeed CMOS TTL-compatible bus switches.

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

Features

s 4Ω switch connection between two ports s Undershoot Hardened to -2.0V. s Minimal propagation delay through the switch s Low lCC. s Zero ground bounce in flow-through mode s Control inputs compatible with TTL level s See.

FSTU3384 10-Bit Bus Switch with May 1999 Revised December 1999 FSTU3384 10-Bit Bus Switch with −2V Undershoot Hardened Circuit (UHC) Protection General Description The Fairchild Switch FSTU3384 provides 10 bits of highspeed CMOS TTL-compatible bus switches. The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay generating additional ground bounce noise. Both the A Ports and the B Ports are “undershoot hardened” with UHC protection to support an extended input range to 2.0V below ground. Fairchild’s integrated Undershoot Hardened Circuit, UHC senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning on the switch.
