SN74AVC16722 22-BIT FLIP-FLOP WITH 3-STATE OUTPUTS SCES166H – DECEMBER 1998 – REVISED JUNE 2000 D D D D D Member of the Texas Instruments Widebus  Family EPIC  (Enhanced-Performance Implanted CMOS) Submicron Process DOC  (Dynamic Output Control) Circuit Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of ±24 mA at 2.5-V VCC D D D Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications Ioff Supports Partial-Power-Down Mode Operation Latch-Up Performance Exceeds 100 mA Per JESD 78, Class I Packaged in Thin Shrink Small-Outline Package description 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. 3.2 TA = 25°C Process = Nominal – Output Voltage – V 2.8 2.4 VCC = 3.3 V 2.0 1.6 VCC = 2.5 V 1.2 OH VCC = 1.8 V 0.8 V VOL – Output Voltage – V 2.8 TA = 25°C Process = Nominal 2.4 2.0 1.6 1.2 0.8 VCC = 3.3 V VCC = 2.5 V 0.4 0.4 0 17 34 51 68 85 102 119 IOL – Output Current – mA 136 153 170 VCC = 1.8 V –160 –144 –128 –112 –96 –80 –64 –48 IOH – Output Current – mA –32 –16 0 Figure 1. Output Voltage vs Output Current This 22-bit 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 22 flip-flops of the SN74AVC16722 are edge-triggered D-type flip-flops with clock-enable (CLKEN) input. On the positive transition of the clock (CLK) input, the device stores data into the flip-flops if CLKEN is low. If CLKEN is high, no data is stored. A buffered output-enable (OE) input places the 22 outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. OE does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs are in the high-impedance state. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 1 SN74AVC16722 22-BIT FLIP-FLOP WITH 3-STATE OUTPUTS SCES166H – DECEMBER 1998 – REVISED JUNE 2000 description (continued) 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 SN74AVC16722 is characterized for operation from –40°C to 85°C. terminal assignments DGG PACKAGE (TOP VIEW) OE Q1 Q2 GND Q3 Q4 VCC Q5 Q6 Q7 GND Q8 Q9 Q10 Q11 Q12 Q13 GND Q14 Q15 Q16 VCC Q17 Q18 GND Q19 Q20 VCC Q21 Q22 GND NC 1 64 2 63 3 62 4 61 5 60 6 59 7 58 8 57 9 56 10 55 11 54 12 53 13 52 14 51 15 50 16 49 17 48 18 47 19 46 20 45 21 44 22 43 23 42 24 41 25 40 26 39 27 38 28 37 29 36 30 35 31 34 32 33 CLK D1 D2 GND D3 D4 VCC D5 D6 D7 GND D8 D9 D10 D11 D12 D13 GND D14 D15 D16 VCC D17 D18 GND D19 D20 VCC D21 D22 GND CLKEN NC – No internal connection 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SN74AVC16722 22-BIT FLIP-FLOP WITH 3-STATE OUTPUTS SCES166H – DECEMBER 1998 – REVISED JUNE 2000 FUNCTION TABLE (each flip-flop) INPUTS D OUTPUT Q X X Q0 ↑ H H OE CLKEN CLK L H L L L L ↑ L L L L L or H X Q0 H X X X Z logic diagram (positive logic) 1 OE 64 CLK 33 CE CLKEN C1 63 D1 1D 2 Q1 To 21 Other Channels absolute maximum ratings over operating free-air temperature range (unless otherwise noted)† Supply voltage range, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 4.6 V Input voltage range, VI (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 4.6 V Voltage range applied to any output in the high-impedance or power-off state, VO (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 4.6 V Voltage range applied to any output in the high or low state, VO (see Notes 1 and 2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to VCC + 0.5 V Input clamp current, IIK (VI < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –50 mA Output clamp current, IOK (VO < 0) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –50 mA Continuous output current, IO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±50 mA Continuous current through each VCC or GND . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±100 mA Package thermal impedance, θJA (see Note 3) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55°C/W Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65°C to 150°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 may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. 2. The output positive-voltage rating may be exceeded up to 4.6 V maximum if the output current rating is observed. 3. The package thermal impedance is calculated in accordance with JESD 51.
