Philips Semiconductors FAST Products
9-Bit latched bidirectional Futurebus transceivers
(open-collector)
Product specification
74F8962/8963
FEATURES
Octal latched transceiver
Drives heavily loaded backplanes with
equivalent load impedances down to 10
High drive (100mA) open collector drivers
on B port
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 futurebus
standards
Built–in precision band–gap reference
provides accurate receiver thresholds and
improved noise immunity
Multiple GND pins minimize ground bounce
Glitch–free power up/power down
operation
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’ (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.
Incident wave switching to 9is 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.
