INTEGRATED CIRCUITS 74ALVT16952 2.5V/3.3V ALVT 16-bit registered transceiver (3-State) Product specification Supersedes data of 1995 Sep 19 IC23 Data Handbook 1998 Mar 19 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) FEATURES 74ALVT16952 DESCRIPTION • Two 8-bit registered transceivers • 5V I/O Compatible • 3-State buffers • Output capability: +64mA/–32mA • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus hold data inputs eliminate the need for external pull-up The 74ALVT16952 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. The 74ALVT16952 is a dual octal registered transceiver. Two 8-bit registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (nCPXX) provided that the Clock Enable (nCEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (nOEXX) is Low. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. resistors to hold unused inputs • Live insertion/extraction permitted • Power-up 3-State • Power-up reset • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level. and 200V per Machine Model QUICK REFERENCE DATA SYMBOL tPLH tPHL Propagation delay nCPBA to nAx or nCPAB to nBx CIN Input capacitance CI/O I/O pin capacitance ICCZ Total supply current TYPICAL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER UNIT 2.5V 3.3V 3.0 3.0 2.3 2.3 ns VI = 0V or VCC VI/O = 0V or VCC Outputs disabled 3 3 pF 9 9 pF Outputs disabled 40 70 µA CL = 50pF; ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 56-Pin Plastic SSOP Type III –40°C to +85°C 74ALVT16952 DL AV16952 DL SOT371-1 56-Pin Plastic TSSOP Type II –40°C to +85°C 74ALVT16952 DGG AV16952 DGG SOT364-1 LOGIC SYMBOL (IEEE/IEC) 3 54 56 1 2 55 26 EN1 31 EN2 29 EN3 28 EN4 27 C5 30 C6 EN1 EN2 EN3 EN4 C5 C6 52 15 6 51 16 41 8 49 17 40 9 48 19 38 10 47 20 37 12 45 21 36 13 44 23 34 14 43 24 33 5 2, 3, 6 1, 4, 5 2, 3, 6 1, 4, 5 42 SH00069 1998 Mar 19 2 853-2053 19136 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) PIN CONFIGURATION 74ALVT16952 LOGIC SYMBOL 1OEAB 1 56 1OEBA 1CPAB 2 55 1CPBA 1CEAB 3 54 1CEBA GND 4 53 GND 1A0 5 52 1B0 1A1 6 51 1B1 VCC 7 50 VCC 1A2 8 49 1A3 9 48 1A4 10 GND 5 6 8 9 10 12 13 14 1A0 1A1 1A2 1A3 1A4 1A5 1A6 1A7 2 1CPAB 1B2 3 1CEAB 1OEBA 56 1B3 55 1CPBA 1OEAB 1 47 1B4 54 1CEBA 11 46 GND 1A5 12 45 1B5 1A6 13 44 1B6 1A7 14 43 1B7 2A0 15 42 2B0 2A1 16 41 2B1 2A2 17 40 2B2 GND 18 39 GND 2A3 19 38 2B3 2A4 20 37 2B4 2A5 21 36 2B5 VCC 22 35 VCC 2A6 23 34 2B6 2A7 24 33 2B7 GND 25 32 GND 2CEAB 26 31 2CEBA 2CPAB 27 30 2CPBA 2OEAB 28 29 2OEBA 1B0 1B1 1B2 1B3 1B4 1B5 1B6 1B7 52 51 49 48 47 45 44 43 15 16 17 19 20 21 23 24 2A0 2A1 2A2 2A3 2A4 2A5 2A6 2A7 27 2CPAB 26 2CEAB 2OEBA 29 30 2CPBA 2OEAB 28 31 2CEBA 2B0 2B1 2B2 2B3 2B4 2B5 2B6 2B7 42 41 40 38 37 36 34 33 SH00071 SH00070 PIN DESCRIPTION PIN NUMBER SYMBOL 2, 55 27, 30 1CPAB / 1CPBA 2CPAB / 2CPBA Clock input A to B / Clock input B to A 3, 54, 26, 31 1CEAB / 1CEBA 2CEAB / 2CEBA Clock enable input A to B / Clock enable input B to A 5, 6, 8, 9, 10, 12, 13, 14, 15, 16, 17, 19, 20, 21, 23, 24 1A0 – 1A7 2A0 – 2A7 Data inputs/outputs (A side) 52, 51, 49, 48, 47, 45, 44, 43 42, 41, 40, 38, 37, 36, 34, 33 1B0 – 1B7 2B0 – 2B7 Data inputs/outputs (B side) 1, 56 28, 29 1OEAB / 1OEBA 2OEAB / 2OEBA 4, 11, 18, 25, 32, 39, 46, 53 GND Ground (0V) 7, 22, 35, 50 VCC Positive supply voltage 1998 Mar 19 NAME AND FUNCTION 3 Output enable inputs Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) FUNCTION TABLE for Register nAx or nBx FUNCTION TABLE for Output Enable INPUTS INPUTS nAx or nBx nCPXX nCEXX INTERNAL Q X X H NC Hold data L H ↑ ↑ L L L H Load data 74ALVT16952 OPERATING MODE nOEXX INTERNAL Q nAx or nBx OUTPUTS OPERATING MODE H X Z Disable outputs L L L H L H Enable outputs H = High voltage level L = Low voltage level X = Don’t care XX = AB or BA Z = High impedance ”off” state H = High voltage level L = Low voltage level ↑ = Low-to-High transition X = Don’t care XX = AB or BA NC= No change LOGIC DIAGRAM nCEAB nCPAB nOEAB DETAIL A CE nA0 Q D CP Q CE CP D nB0 nA1 nB1 nA2 nB2 nA3 nA4 nB3 DETAIL A X 7 nB4 nA5 nB5 nA6 nB6 nA7 nB7 nCEBA nCPBA nOEBA SH00072 1998 Mar 19 4 Philips Semiconductors Product specification 2.5V/3.3V 16-bit registered transceiver (3-State) 74ALVT16952 ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK CONDITIONS RATING UNIT –0.5 to +4.6 V –50 mA –0.5 to +7.0 V VO < 0 –50 mA output in Off or High state –0.5 to +7.0 V output in Low state output in High state 128 –64 mA –65 to +150 °C DC supply voltage DC input diode current VI < 0 voltage3 VI DC input IOK DC output diode current voltage3 VOUT DC output IOUT DC output current Tstg Storage temperature range NOTES: 1.
