INTEGRATED CIRCUITS 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) Product specification Supersedes data of 1995 Sep 28 IC23 Data Handbook 1998 Feb 25 Philips Semiconductors Product specification 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) FEATURES DESCRIPTION • Two 8-bit registered transceivers • Live insertion/extraction permitted • Power-up 3-State • 74ABTH16952 incorporates bus-hold data inputs which eliminate The 74ABT16952 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT16952 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. the need for external pull-up resistors to hold unused inputs • Power-up reset • Multiple VCC and GND pins minimize switching noise • Independent registers for A and B buses • Output capability: +64mA/–32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 Two options are available, 74ABT16952 which does not have the bus-hold feature and 74ABTH16952 which incorporates the bus-hold feature. and 200V per Machine Model • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER tPLH tPHL Propagation delay nCPBA to nAx or nCPAB to nBx CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC CI/O I/O capacitance VO = 0V or VCC; 3-State ICCZ UNIT 2.8 2.3 ns 4 pF Outputs disabled; VCC = 5.5V Quiescent su supply ly current ICCL TYPICAL 7 pF 500 µA 8 mA Outputs LOW; VCC = 5.5V ORDERING INFORMATION TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 56-Pin Plastic SSOP Type III PACKAGES –40°C to +85°C 74ABT16952 DL BT16952 DL SOT371-1 56-Pin Plastic TSSOP Type II –40°C to +85°C 74ABT16952 DGG BT16952 DGG SOT364-1 56-Pin Plastic SSOP Type III –40°C to +85°C 74ABTH16952 DL BH16952 DL SOT371-1 56-Pin Plastic TSSOP Type II –40°C to +85°C 74ABTH16952 DGG BH16952 DGG SOT364-1 PIN DESCRIPTION PIN NUMBER SYMBOL 2, 55 18, 22 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 52, 51, 49, 48, 47, 45, 44, 43 42, 41, 40, 38, 37, 36, 34, 33 1A0 – 1A7 2A0 – 2A7 Data inputs/outputs (A side) 1, 56 8, 29 1B0 – 1B7 2B0 – 2B7 Data inputs/outputs (B side) 4, 11, 18, 25, 32, 39, 45, 53 1OEAB / 1OEBA 2OEAB / 2OEBA 4, 17, 30, 43 GND Ground (0V) 7, 22, 35, 50 VCC Positive supply voltage 1998 Feb 25 NAME AND FUNCTION 2 Output enable inputs 853-1814 19018 Philips Semiconductors Product specification 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) PIN CONFIGURATION 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 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 1998 Feb 25 6 3 Philips Semiconductors Product specification 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) LOGIC SYMBOL (IEEE/IEC) FUNCTION TABLE for Register nAx or nBx 1OEBA 56 1EN3 1CEBA 54 G1 1LPBA 55 1C5 1OEAB 1 EN4 INPUTS 1LEAB 3 G2 1CPAB 2 2C6 2OEBA 29 EN9 2CEBA 31 G7 2CPBA 30 7C11 2OEAB 28 EN10 2LEAB 26 G8 2CPAB 27 8C12 5 ∇3 5D 6D 4∇ 1A0 OPERATING MODE nAx or nBx nCPXX nCEXX Q X X H NC Hold data L H ↑ ↑ L L L H Load data H = High voltage level L = Low voltage level ↑ = Low-to-High transition X = Don’t care XX = AB or BA NC= No change FUNCTION TABLE for Output Enable 52 1B0 1A1 6 51 1B1 1A2 8 49 1B2 1A3 9 48 1B3 1A4 10 47 1B4 1A5 12 45 1B5 1A6 13 44 1B6 1A7 14 43 1B7 2A0 15 42 2B0 ∇9 11D 12D 10 ∇ 2A1 16 41 2B1 2A2 17 40 2B2 2A3 19 38 2B3 2A4 20 37 2B4 2A5 21 36 2B5 2A6 23 34 2B6 2A7 24 33 2B7 INPUTS INTERNAL nAx or nBx OPERATING nOEXX Q OUTPUTS 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 SH00086 1998 Feb 25 INTERNAL 4 Philips Semiconductors Product specification 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) 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 Feb 25 5 Philips Semiconductors Product specification 74ABT16952 74ABTH16952 16-bit registered transceiver (3-State) ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK CONDITIONS RATING UNIT –0.5 to +7.0 V –18 mA –1.2 to +7.0 V VO < 0 –50 mA Output in Off or High state –0.5 to +5.5 V Output in Low state 128 Output in High state –64 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 out ut current Tstg Storage temperature range mA –65 to 150 °C NOTES: 1.
