High-Speed CMOS 8-Bit Register with Asynchronous Reset
DESCRIPTION
QS54/74FCT273T
function compatible 74F273 74FCT273 74ABT273 Industrial temperature -40°C 85°C CMOS power levels: <7.5mW static Available SOIC, QSOP, ZIP, HQSOP Undershoot clamp diodes inputs TTL-compatible input output levels Ground bounce controlled outputs Reduced output swing 0-3.5V Military product compliant MIL-STD-883, Class FCT-T 273T JEDEC-FCT spec compatible speed grades with 5.2ns 48mA Ind., 32mA Mil.
QSFCT273T high-speed CMOS TTLcompatible 8-bit registers with asynchronous reset input, buffered common clock, buffered output drive. Data stored register rising edge clock. high output current drive high capacitance loads. inputs have clamp diodes undershoot noise suppression. outputs have ground bounce suppression (see Application Note AN-001), outputs will load active when removed from device.
