SN54HC245J Description

Short technical summary and product information.

The SN54HC245J from Texas Instruments is an octal bus transceiver designed for asynchronous two-way communication between data buses. This device operates within a wide voltage range of 2 V to 6 V and features high-current 3-state outputs capable of driving bus lines directly or up to 15 LSTTL loads.

Key electrical characteristics include 8 channels, CMOS input and output types, and a typical propagation delay of 12 ns. The transceiver offers balanced outputs and positive input clamp diodes. It has a low power consumption of 80 μA maximum Icc and a low input current of 1 μA maximum.

The SN54HC245J is rated for military applications and operates across a temperature range of -55 to 125 °C. It is available in CDIP (J), CFP (W), and LCCC (FK) packages. The control-function implementation minimizes external timing requirements, allowing data transmission from the A bus to the B bus or vice versa, controlled by the direction-control (DIR) input. The output-enable (OE) input can disable the device, effectively isolating the buses.
