FEATURES:
DESCRIPTION:
DRIVE FEATURES:
High Output Drivers: ±24mA Suitable Heavy Loads
32-bit transparent D-type latch built using advanced dual metal CMOS technology. high-speed, low-power latch ideal temporary storage data. device used implementing memory address latches, ports, drivers. Output Enable Latch Enable controls organized operate each device four 8-bit latches, 16bit latches, 32-bit latch. Flow-through organization signal pins simplifies layout. inputs designed with hysteresis improved noise margin. ALVCH32373 been designed with ±24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance. ALVCH32373 "bus-hold" which retains inputs' last state whenever input goes high impedance. This prevents floating inputs eliminates need pull-up/down resistor.
APPLICATIONS:
3.3V high speed systems 3.3V lower voltage computing systems
