16ĆBIT TRIĆPORT UNIVERSAL BUS EXCHANGERS
ą
SCBS179A − JUNE 1992 − REVISED JULY 1994
• Members of the Texas Instruments
Widebus +  Family
• State-of-the-Art EPIC-ΙΙB BiCMOS Design
Significantly Reduces Power Dissipation
• UBE  (Universal Bus Exchanger)
Combines D-Type Latches and D-Type
Flip-Flops for Operation in Transparent,
Latched, Clocked, or Clock-Enabled Mode
• ESD Protection Exceeds 2000 V
Per MIL-STD-883C, Method 3015
• Latch-Up Performance Exceeds 500 mA
Per JEDEC Standard JESD-17
• Typical V_OLP (Output Ground Bounce)
< 0.8 V at V_CC = 5 V, T_A = 25°C
• Distributed V_CC and GND Pin Configuration
Minimizes High-Speed Switching Noise
• High-Drive Outputs (− 32-mA I_OH,
64-mA I_OL )
• Bus Hold on Data Inputs Eliminates the
Need for External Pullup/Pulldown
Resistors
