DESCRIPTION
LVCH16374A 16-bit edge-triggered D-type register built using advanced dual metal CMOS technology. This high-speed, low-power register ideal buffer register data synchronization storage. Output Enable (OE) clock (CLK) controls organized operate each device 8-bit registers 16-bit register with common clock. Flow-through organization signal pins simplifies layout. inputs designed with hysteresis improved noise margin. pins LVCH16374A driven from either 3.3V devices. This feature allows this device translator mixed 3.3V/5V supply system. LVCH16374A been designed with 24mA output driver. This driver capable driving moderate heavy load while maintaining speed performance. LVCH16374A "bus-hold" which retains inputs' last state whenever input goes high impedance. This prevents floating inputs eliminates need pull-up/down resistors.
DRIVE High Output Drivers: ±24mA Reduced system switching noise
