Description

The Intersil HCTS245MS is a Radiation Hardened Non- Inverting Octal Bidirectional Bus Transceiver, Three-State, intended for two-way asynchronous communication between data busses. The HCTS245MS allows data transmission from the A bus to the B bus or from the B bus to the A bus. The logic level at the direction input (DIR) determines the data direction. The output enable input (OE) puts the I/O port in the high-impedance state when high.

The HCTS245MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family. The HCTS245MS is supplied in a 20 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
