Логическая ИС SN74LS245DW

Приемопередатчик , неинвертирующий, 3 состояния, 4.75В до 5.25В, SOIC-20

The SN74LS245DW is an Octal Bus Transceiver designed for asynchronous two-way communication between data buses. The control-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 on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can disable the device so that the buses are effectively isolated.

• 3-state Outputs drive bus lines directly
• PNP inputs reduce DC loading on bus lines
• Hysteresis at bus inputs improves noise margins
• 8ns Typical propagation delay times port to port
