74F8963

Philips Semiconductors FAST Products Product specification 9-Bit latched bidirectional Futurebus transceivers (open-collector) Multiple GND pins minimize ground bounce Glitch–free power up/power down operation 74F8962/8963 FEATURES Octal latched transceiver Drives heavily loaded backplanes with on B port power consumption and a series diode on the drivers to reduce capacitive loading. Incident wave switching to 9Ω is guaranteed. The voltage swing is much less for BTL, so is its receiver threshold region, therefore noise margins are excellent. BTL offers low power consumption, low ground bounce, EMI and crosstalk, low capacitive loading, superior noise margin and low propagation delays. This results in a high bandwidth, reliable backplane. The 74F8962 and 74F8963 A ports have TTL 3-state drivers and TTL receivers with a latch function. The 74F8963 is the non-inverting version of 74F8962. equivalent load impedances down to 10Ω High drive (100mA) open collector drivers Reduced voltage swing (1 volt) produces less noise and reduces power consumption DESCRIPTION The 74F8962 and 74F8963 are octal bidirectional latched transceivers and are intended to provide the electrical interface to a high performance wired-OR bus. The B port inverting drivers are low-capacitance open collector with controlled ramp and are designed to sink 100mA from 2 volts. The B port inverting receivers have a 150mV threshold region. The B port interfaces to ‘Backplane Transceiver Logic’ ...
