EDGE-TRIGGERED D-TYPE
FLIP-FLOP WITH 3-STATE
OUTPUTS
AND BUS-HOLD
DESCRIPTION:
This octal postive edge-triggered D-type flip-flop is built using advanced
dual metal CMOS technology. The ALVCH374 device is particularly
suitable for implementing buffer registers, I/O ports, bidirectional bus
drivers, and working registers. On the positive transition of the clock (CLK)
input, the Q outputs are set to the logic levels at the data (D) inputs.
A buffered output-enable (
OE
) input 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 increased
drive provide the capability to drive bus lines without interface or pullup
components.
OE
does not affect internal operations of the latch. Old data
can be retained or new data can be entered while the outputs are in the
high-impedance state.
The ALVCH374 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The ALVCH374 has a “bus-hold” which retains the inputs’ last state
whenever the input bus goes to a high impedance. This prevents floating
inputs and elimnates the need for pull-up/down resistors.
