description
This 16-bit edge-triggered D-type flip-flop is
designed for 1.65-V to 3.6-V V
CC
operation.
The SN74ALVCH16374 is particularly suitable for
implementing
buffer
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 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 the
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.
registers,
I/O
ports,
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.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16374 is characterized for operation from –40
°
C to 85
°
C.
