SN74HCT245

SN54HCT245, SN74HCT245 SCLS020H – MARCH 1984 – REVISED DECEMBER 2022 SNx4HCT245 Octal Bus Transceivers With 3-State Outputs 1 Features Operating voltage range of 4.5 V to 5.5 V High-Current 3-state outputs drive bus lines directly or up to 15-LSTTL loads Low power consumption, 80-µA maximum ICC Typical tpd = 14 ns ±6-mA output drive at 5 V Low input current of 1 µA maximum Inputs are TTL-voltage compatible 2 Applications Factory Automation and Control Grid Infrastructure Electronic Point of Sale Multi-Function Printers Motor Drives Storage Telecom Infrastructure DIR 1 3 Description The SNx4HCT245 octal bus transceivers are designed for asynchronous two-way communication between data buses. The controlfunction implementation minimizes external timing requirements. The SNx4HCT245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the directioncontrol (DIR) input. The output-enable ( OE) input can be used to disable the device so that the buses are effectively isolated.
