PI74FCT399T FAST CMOS QUAD DUAL-PORT REGISTER
PI74FCT399T
Fast CMOS Quad Dual-Port Register
Product Features
Product Description
Pericom Semiconductors PI74FCT series of logic circuits are produced in the Companys advanced 0.8 micron CMOS technology, achieving industry leading speed grades. These high-speed quad dual-port registers select 4-bit wide data from one of the two sources (Ports) under control of a common Select input (S). Synchronous with the LOW-to-HIGH transition of the Clock input (CP), the selected data is transferred to a 4-bit output register. The 4-bit D-type output register is fully edge-triggered. For predictable operation, the Data inputs (IAX, IBX) and Select input (S) must be stable one set-up time prior to, and hold time after, the LOW-to-HIGH transition of the Clock input.
PI74FCT399T is pin compatible with bipolar FAST Series at a higher speed and lower power consumption TTL input and output levels Extremely low static power Hysteresis on all inputs Industrial operating temperature range: 40°C to +85°C Packages available: 16-pin 300 mil wide plastic DIP (P) 16-pin 150 mil wide plastic QSOP (Q) 16-pin 300 mil wide plastic SOIC (S) 16-pin 150 mil wide plastic SOIC (W)
