The control-function implementation minimizes Directly or Up to 15 LSTTL Loads external timing requirements. • Low Power Consumption, 80- μA Max ICC The devices allow data transmission from the A bus • Typical tpd = 12 ns to the B bus or from the B bus to the A bus, • ±6-mA Output Drive at 5 V depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be • Low Input Current of 1 μA Max used to disable the device so that the buses are • On Products Compliant to MIL-PRF-38535, effectively isolated. All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Device Information Processing Does Not Necessarily Include Testing PART NUMBER PACKAGE BODY SIZE (NOM) of All Parameters.
