DESCRIPTION:
The LVCH162374A 16-bit edge-triggered D-type flip-flop is built using
advanced dual metal CMOS technology. This high-speed, low-power
register is ideal for use as a buffer register for data synchronization and
storage. The output enable (OE) and clock (CLK) controls are organized
to operate each device as two 8-bit registers or one 16-bit register with
common clock. Flow-through organization of signal pins simplifies layout.
All inputs are designed with hysteresis for improved noise margin.
All pins of the LVCH162374A can be driven from either 3.3V or 5V
devices. This feature allows the use of this device as a translator in a mixed
3.3V/5V supply system.
The LVCH162374A has series resistors in the device output structure
which will significantly reduce line noise when used with light loads. This
driver has been developed to drive ±12mA at the designated thresholds.
The LVCH162374A has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
