VIL = 0.8V (MAX) SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL PIN AND FUNCTION COMPATIBLE WITH 54 SERIES 245 SPACE GRADE-1: ESA SCC QUALIFIED 50 krad QUALIFIED, 100 krad AVAILABLE ON REQUEST NO SEL UNDER HIGH LET HEAVY IONS IRRADIATION DEVICE FULLY COMPLIANT WITH SCC-9405-014
DESCRIPTION The is an advanced high-speed CMOS OCTAL BUS TRANSCEIVER (3-STATE) fabricated with silicon gate C2MOS technology. This IC is intended for two-way asynchronous communication between data buses, and the
direction of data transmission is determined by DIR input. The enable input G can be used to disable the device so that the buses are effectively isolated. All inputs are equipped with protection circuits against static discharge and transient excess voltage. All floating bus terminals during High Z State must be held HIGH or LOW.Output Enable Input Ground (0V) Positive Supply Voltage
