Description

The Intersil HCTS299MS is a Radiation Hardened 8-bit shift/

storage register with three-state bus interface capability. The

register has four synchronous operating modes controlled by

the two select inputs (S0, S1). The mode select, the serial

data (DS0, DS7) and the parallel data (IO0 - IO7) respond

only to the low to high transition of the clock (CP) pulse. S0,

S1 and the data inputs must be one set up time period prior

to the clocks positive transition. The master reset (MR) is an

asynchronous active low input.

The HCTS299MS utilizes advanced CMOS/SOS technology

to achieve high-speed operation. This device is a member of

radiation hardened, high-speed, CMOS/SOS Logic Family

with TTL input compatibility.
