SN74LVCH16374A
16-BIT EDGE-TRIGGERED D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUTS
SCAS757A – DECEMBER 2003 – REVISED OCTOBER 2005
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 the 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 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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in
a mixed 3.3-V/5-V system environment.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors
with the bus-hold circuitry is not recommended.
The SN74LVCH16374A 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.
This device is fully specified for partial-power-down applications using I
off. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
