High-Speed CMOS 8-Bit Register with Clock Enable
DESCRIPTION
QS54/74FCT377T QS54/74FCT2377T
function compatible 74F377 74FCT377 74ABT377 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 377T JEDEC-FCT spec compatible speed grades with 5.2ns 48mA Ind., 32mA Mil. FCT-T 2377T Built-in series resistor outputs reduce reflection other system noise speed grades with 5.2ns 12mA Ind.
QSFCT377T QSFCT2377T high-speed CMOS TTL-compatible 8-bit registers, with buffered common clock, buffered output drive, synchronous clock enable. QSFCT2377T resistor output version useful driving transmission lines reducing system noise. Data stored register rising edge clock clock enable input active. 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.
