DESCRIPTION

The 74F3893 is a quad backplane transceivers and is intended to be used in very high speed bus systems.

The 74F3893 interfaces to ‘Backplane Transceiver Logic’ (BTL). BTL features a reduced (1V to 2V) voltage swing for lower power consumption and a series diode on the drivers to reduce capacitive loading (< 5pF).

FEATURES

• Quad backplane transceiver

• Drives heavily loaded backplanes with equivalent load impedances down to 10 ohms

• Futurebus drivers sink 100mA

• Reduced voltage swing (1 volt) produces less noise and reduces power consumption

• High speed operation enhances performance of backplane buses and facilitates incident wave switching

• Compatible with IEEE 896 and IEEE 1194.1 Futurebus Standards

• Built–in precision band–gap (BG) reference provides accurate receiver thresholds and improved noise immunity

• Glitch–free power up/power down operation on all outputs

• Pin and function compatible with NSC DS3893
