INTEGRATED CIRCUITS 74ALVT16821 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) Product specification Supersedes data of 1997 May 01 IC24 Data Handbook 1998 Feb 13 Philips Semiconductors Product specification 2.5V/3.3V 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) FEATURES 74ALVT16821 DESCRIPTION • 20-bit positive-edge triggered register • 5V I/O Compatible • Multiple VCC and GND pins minimize switching noise • Live insertion/extraction permitted • Power-up reset • Power-up 3-State • Output capability: +64mA/-32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 The 74ALVT16821 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. It is designed for VCC operation at 2.5V or 3.3V with I/O compatibility to 5V. The 74ALVT16821 has two 10-bit, edge triggered registers, with each register coupled to a 3-State output buffer. The two sections of each register are controlled independently by the clock (nCP) and Output Enable (nOE) control gates. Each register is fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output. The 3-State output buffers are designed to drive heavily loaded 3-State buses, MOS memories, or MOS microprocessors. and 200V per Machine Model • Bus hold data inputs eliminate the need for external pull-up The active Low Output Enable (nOE) controls all ten 3-State buffers independent of the register operation. When nOE is Low, the data in the register appears at the outputs. When nOE is High, the outputs are in high impedance “off” state, which means they will neither drive nor load the bus. resistors to hold unused inputs QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C PARAMETER TYPICAL UNIT 2.5V 3.3V 2.6 2.7 1.7 1.8 ns tPLH tPHL Propagation delay nCP to nQ CL = 50pF CIN Input capacitance VI = 0V or VCC 3 3 pF COUT Output capacitance VO = 0 or VCC 9 9 pF ICCZ Total supply current Outputs disabled 40 70 µA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 56-Pin Plastic SSOP Type III –40°C to +85°C 74ALVT16821 DL AV16821 DL SOT371-1 56-Pin Plastic TSSOP Type II –40°C to +85°C 74ALVT16821 DGG AV16821 DGG SOT364-1 1998 Feb 13 2 853-1869 18962 Philips Semiconductors Product specification 2.5V/3.3V 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) LOGIC SYMBOL 56 54 74ALVT16821 PIN CONFIGURATION 52 51 49 48 47 1D0 1D1 1D2 1D3 1D4 1D5 1D6 45 44 43 1D7 1D8 1D9 1OE 1 56 1CP 1Q0 2 55 1D0 56 1CP 1Q1 3 54 1D1 1 1OE GND 4 53 GND 1Q2 5 52 1D2 1Q3 6 51 1D3 VCC 7 50 VCC 1Q4 8 49 1D4 1Q5 9 48 1D5 1Q6 10 47 1D6 GND 11 46 GND 1Q7 12 45 1D7 1Q8 13 44 1D8 1Q9 14 43 1D9 2Q0 15 42 2D0 2Q1 16 41 2D1 2Q2 17 40 2D2 GND 18 39 GND 2Q3 19 38 2D3 2Q4 20 37 2D4 2Q5 21 36 2D5 VCC 22 35 VCC 2Q6 23 34 2D6 2Q7 24 33 2D7 1Q0 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 1Q9 2 3 42 41 5 40 6 38 8 37 9 36 10 34 2D0 2D1 2D2 2D3 2D4 2D5 2D6 29 12 33 13 14 31 30 2D7 2D8 2D9 2CP 28 2OE 2Q0 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 2Q9 15 16 17 19 20 21 23 24 26 27 SH00002 LOGIC SYMBOL (IEEE/IEC) 1OE 1 1CP 56 2OE 28 2CP 29 1D0 55 1D1 EN2 C1 EN4 C3 2 1Q0 GND 25 32 GND 54 3 1Q1 2Q8 26 31 2D8 1D2 52 5 1Q2 2Q9 27 30 2D9 1D3 51 6 1Q3 2OE 28 29 2CP 1D4 49 8 1Q4 1D5 48 9 1Q5 1D6 47 10 1Q6 1D7 45 12 1Q7 1D8 44 13 1Q8 1D9 43 14 1Q9 2D0 42 15 2Q0 2D1 41 16 2Q1 2D2 40 17 2Q2 2D3 38 19 2Q3 2D4 37 20 2Q4 2D5 36 21 2Q5 2D6 34 23 2Q6 2D7 33 24 2Q7 2D8 31 26 2Q8 2D9 30 27 2Q9 1D 3D 2∇ 4∇ SH00001 SH00003 1998 Feb 13 3 Philips Semiconductors Product specification 2.5V/3.3V 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) PIN DESCRIPTION PIN NUMBER FUNCTION TABLE SYMBOL 56, 54, 52, 51, 49, 48, 47, 45, 44, 43, 42, 41, 40, 38, 37, 36, 34, 33, 31, 30 74ALVT16821 INPUTS FUNCTION 1D0 - 1D9 2D0 - 2D9 Data inputs 2, 3, 5, 6, 8, 9, 10, 12, 13, 14, 15, 16, 17, 19, 20, 21, 23, 24, 26, 27 1Q0 - 1Q9 2Q0 - 2Q9 Data outputs 1, 28 1OE, 2OE Output enable inputs (active-Low) 56, 29 1CP, 2CP Clock pulse inputs (active rising edge) 4, 11, 18, 25, 32, 39, 46, 53 GND Ground (0V) 7, 22, 35, 50 VCC Positive supply voltage OUTPUTS nQ0 - nQ9 OPERATING MODE nOE nCP nDx INTERNAL REGISTER L L ↑ ↑ l h L H L H Load and read register L ↑ X NC NC Hold H ↑ X NC Z Disable ↑ H Dn Dn Z outputs H = High voltage level h = High voltage level one set-up time prior to the Low-to-High clock transition L = Low voltage level l = Low voltage level one set-up time prior to the Low-to-High clock transition NC= No change X = Don’t care Z = High impedance “off” state ↑ = Low to High clock transition ↑ = Not a Low-to-High clock transition LOGIC DIAGRAM nD0 nD1 nD2 nD3 nD4 nD5 nD6 nD7 nD8 nD9 D D D D D D D D D D CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q CP Q nCP nOE nQ0 nQ1 nQ2 nQ3 nQ4 nQ5 nQ6 nQ7 nQ8 nQ9 SH00004 1998 Feb 13 4 Philips Semiconductors Product specification 2.5V/3.3V 20-bit bus-interface D-type flip-flop; positive-edge trigger (3-State) 74ALVT16821 ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC CONDITIONS RATING UNIT –0.5 to +4.6 V –50 mA –1.2 to +7.0 V VO < 0 –50 mA Output in Off or High state –0.5 to +7.0 V Output in Low state 128 Output in High state –64 DC supply voltage IIK DC input diode current VI DC input voltage3 IOK DC output diode current VI < 0 VOUT DC output voltage3 IOUT O DC output current Tstg Storage temperature range mA °C –65 to 150 NOTES: 1.
