Product Description: Product Features:
Common Features:5 · PI74FCT16500T and PI74FCT162500T are high-speed, low power devices with high current drive. · VCC = 5V ±10% · Hysteresis on all inputs · Packages available: 56-pin 240 mil wide plastic TSSOP (A) 56-pin 300 mil wide plastic SSOP (V) PI74FCT16500T Features: · High output drive: IOH = 32 mA; IOL = 64 mA · Power off disable outputs permit "live insertion" · Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, TA = 25°C PI74FCT162500T Features: · Balanced output drivers: ±24 mA · Reduced system switching noise · Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, TA = 25°C Pericom Semiconductor's PI74FCT series of logic circuits are produced in the Company's advanced 0.8 micron CMOS technology, achieving industry leading speed grades. The PI74FCT16500T and PI74FCT162500T are 18-bit registered bus transceivers designed with D-type latches and flip-flops to allow data flow in transparent, latched, and clocked modes. The Output Enable (OEAB and OEBA), Latch Enable (LEAB and LEBA) and Clock (CLKAB and CLKBA) inputs control the data flow in each direction. When LEAB is HIGH, the device operates in transparent mode for A-to-B data flow. When LEAB is LOW, the A data is latched if CLKAB is held at a HIGH or LOW logic level. The A bus data is stored in the latch/flip-flop on the HIGH-to-LOW transition of CLKAB, if LEAB is LOW. OEAB performs the output enable function on the B port. Data flow from B port to A port is similar using OEBA, LEBA and CLKBA. These high-speed, low power devices offer a flow-through organization for ease of board layout. The PI74FCT16500T output buffers are designed with a Power-Off disable allowing "live insertion" of boards when used as backplane drivers. The PI74FCT162500T has ±24 mA balanced output drivers. It is designed with current limiting resistors at its outputs to control the output edge rate resulting in lower ground bounce and undershoot. This eliminates the need for external terminating resistors for most interface applications.
