Product Summary
The SN74HC245DW octal bus transceivers is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The SN74HC245DW allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
Parametrics
SN74HC245DW absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input clamp current, IIK (VI < 0 or VI > VCC): ±20 mA; (3)Output clamp current, IOK (VO < 0 or VO > VCC): ±20 mA; (4)Continuous output current, IO (VO = 0 to VCC): ±35 mA; (5)Continuous current through VCC or GND: ±70 mA; (6)Storage temperature range, Tstg: –65℃ to 150℃.
Features
SN74HC245DW features: (1)Wide Operating Voltage Range of 2 V to 6 V; (2)High-Current 3-State Outputs Drive Bus; (3)Lines Directly or Up To 15 LSTTL Loads; (4)Low Power Consumption, 80-μA Max ICC; (5)Typical tpd = 12 ns; (6)±6-mA Output Drive at 5 V; (7)Low Input Current of 1 μA Max.
