Am29800 series (5 * MIlitary product compliant to MIL-STD-883, Class B * Available in the following packages: - Commercial: SOIC - Military: CERDIP, LCC The FCT823 series is built using an advanced dual metal CMOS technology. The FCT823 bus interface registers are designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider address/data paths or buses carrying parity. The FCT823 is a 9-bit wide buffered register with Clock Enable (EN) and Clear (CLR) - ideal for parity bus interfacing in high-performance microprogrammed systems. The FCT823 high-performance interface family is designed for highcapacitance load drive capability, while providing low-capacitance bus loading at both inputs and outputs. All inputs have clamp diodes and all outputs are designed for low-capacitance bus loading in high-impedance state.

When the clear input is HIGH, data can be entered into the register. CP I Clock Pulse for the Register; enters data into the register on the LOW-to-HIGH transition. Yx O Register 3-state outputs EN I Clock Enable. When the clock enable is LOW, data on the DI input is transferred to the QI output on the LOW-to-HIGH clock transition. When the clock enable is HIGH, the QI outputs do not change state, regardless of the data or clock input transitions. OE I Output Control. When the OE input is HIGH, the Yx outputs are in the high impedance state. When the OE input is LOW, the TRUE register data is present at the Yx outputs.
