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).
