PI74FCT16244T PI74FCT162244T Fast CMOS 16-Bit Buffer/Line Drivers Common Features • High-speed, low-power devices with high-current drive VCC = 5V ±10% • Hysteresis on all inputs • Packaging Pb-free & Green available : 48-pin 240-mil wide plastic TSSOP A 48-pin 300-mil wide plastic SSOP V 48-pin 173-mil wide plastic TVSOP K • Device models available upon request PI74FCT16244T Features • High output drive IOH = IOL = 64mA • Power off disable outputs permit "live insertion" • Typical VOLP Output Ground Bounce < 1.0V at VCC = 5V, TA = 25°C PI74FCT162244T Features • Balanced output drivers ±24mA • Reduced system switching noise • Typical VOLP Output Ground Bounce < 0.6V at VCC = 5V, TA = 25°C Pericom Semiconductor’s PI74FCT16244T and PI74FCT162244T are non-inverting 16-bit buffer/line drivers designed for applications driving high capacitance loads and low impedance backplanes. These high-speed, low power devices offer bus/backplane interface capability and a flow-through organization for ease of board layout. These devices are designed with three-state controls to operate in a Quad-Nibble, Dual-Byte, or a single 16-bit word mode. The PI74FCT16244T output buffers are designed with a Power-Off disable allowing “live insertion” of boards when used as backplane drivers. The PI74FCT162244T has ±24mA 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.
