Product Summary

These octal bus transceivers are designed for asynchronous two-way communication between data buses. Thecontrol-function implementation minimizes external timing requirements.The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending onthe logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable thedevice so that the buses are effectively isolated.

Parametrics

Absolute maximum ratings over operating free-air temperature range (unless otherwise noted):
(1)Supply voltage range, VCC:-0.5 V to 7 V;
(2)Input clamp current, IIK (VI < 0 or VI > VCC) (see Note 1):±20mA;
(3)Output clamp current, IOK (VO < 0 or VO > VCC) (see Note 1):±20 mA;
(4)Continuous output current, IO (VO = 0 to VCC):±35 mA;
(5)Continuous current through VCC or GND:±70 mA;
(6)Package thermal impedance,θJA (see Note 2): N package:69℃/W;
(7)Storage temperature range, Tstg:–65℃ to 150℃

Features

(1)Wide Operating Voltage Range of 2 V to 6 V; (2)High-Current 3-State Outputs Drive Bus,Lines Directly or Up To 15 LSTTL Loads; (3)Low Power Consumption, 80-μA Max ICC; (4)Typical tpd = 12 ns; (5)±6-mA Output Drive at 5 V; (6)Low Input Current of 1 μA Max
