DESCRIPTION/ORDERING INFORMATION
A Dynamic Output Control (DOC) circuit is implemented, which, during the transition, initially lowers the output
impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1 shows
typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the circuit. At
the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is equivalent to a
high-drive standard-output device. For more information, refer to the TI application reports, AVC Logic Family
Technology and Applications, literature number SCEA006, and Dynamic Output Control (DOC) Circuitry
Technology and Applications, literature number SCEA009.

SN74AVC16374
16-BIT EDGE-TRIGGERED D-TYPE FLIP-FLOP
WITH 3-STATE OUTPUTS
www.ti.com
SCES158H – DECEMBER 1998 – REVISED MARCH 2005
DESCRIPTION/ORDERING INFORMATION (CONTINUED)
This 16-bit edge-triggered D-type flip-flop is operational at 1.2-V to 3.6-V VCC, but is designed specifically for
1.65-V to 3.6-V VCC operation.
The SN74AVC16374 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 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.
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.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74AVC16374 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.
The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current ratings is observed.
The package thermal impedance is calculated in accordance with JESD 51.

NOTES: A. CL includes probe and jig capacitance.
B. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.
C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, tr ≤ 2 ns, tf ≤ 2 ns.
D. The outputs are measured one at a time, with one transition per measurement.
E. tPLZ and tPHZ are the same as tdis.
F. tPZL and tPZH are the same as ten.
G. tPLH and tPHL are the same as tpd.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
