FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
This 16-bit edge-triggered D-type flip-flop is built using advanced dual metal
CMOS technology. The ALVCH162374 is particularly suitable for implementing
buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can
be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of
the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up
at the data (D) inputs. OE can be used to place the eight outputs in either a normal
logic state (high or low logic levels) or a high-impedance state. In the high-
impedance state, the outputs neither load nor drive the bus lines significantly.
The high-impedance state and the increased drive provide the capability to
drive bus lines without need for interface or pullup components. OE does not
affect internal operations of the flip-flop. Old data can be retained or new data
can be entered while the outputs are in the high-impedance state.
The ALVCH162374 has series resistors in the device output structure which
will significantly reduce line noise when used with light loads. This driver has
been designed to drive ±12mA at the designated threshold levels.
The ALVCH162374 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 resistor.
DRIVE FEATURES:
• Balanced Output Drivers: ±12mA
• Low switching noise
