DESCRIPTION 74V1T77 advanced high-speed CMOS SINGLE D-TYPE LATCH fabricated with sub-micron silicon gate double-layer metal wiring C2MOS technology. designed operate from 4.5V 5.5V, making this device ideal portable applications. single D-Type latch controlled Latch Enable Input (LE). While input held high level, output will follow data input precisely. When input taken
output latched precisely logic level data input. Power down protection provided inputs accepted inputs with regard supply voltage. This device used interface It's available commercial extended temperature range. inputs output equipped with protection circuits against static discharge, giving them immunity transient excess voltage.
