SNJ54HCT245J Description

Short technical summary and product information.

The Texas Instruments SNJ54HCT245J is an active octal bus transceiver designed for asynchronous two-way communication between data buses. This device allows 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.

 

Key electrical specifications include 8 channels, TTL input type, and CMOS output type. It operates within a voltage range of 4.5 V to 5.5 V, with a maximum Icc of 80 μA and a low input current of 1 μA. The transceiver offers balanced outputs and high speed with a typical propagation delay of 14 ns. The output drive is ±6 mA at 5 V.

 

This transceiver is rated for military operating temperature ranges from -55°C to 125°C. It is available in CDIP (J), CFP (W), and LCCC (FK) packages, all with 20 pins. The positive input clamp diode feature aids in reducing transmission line effects.

 

The SNJ54HCT245J is suitable for applications requiring reliable data transfer between different data buses where TTL input compatibility and CMOS output drive are necessary.
