INTEGRATED CIRCUITS 74ABT2952 Octal registered transceiver (3-State) Product specification Supersedes data of 1995 Jun 15 IC23 Data Handbook 1998 Feb 11 Philips Semiconductors Product specification Octal registered transceiver (3-State) FEATURES 74ABT2952 DESCRIPTION • 8-bit registered transceiver • 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 The 74ABT2952 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT2952 device is an 8-bit registered transceiver. Two 8-bit back-to-back 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 (CPXX) provided that the Clock Enable (CEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. and 200V per Machine Model • Power-up 3-State • Power-up reset • Live insertion/extraction permitted QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 5.7 ns tPLH tPHL Propagation delay CPBA to An or CPAB to Bn CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC 4 pF CI/O I/O capacitance Outputs disabled; VO = 0V or VCC 7 pF ICCZ Total supply current Outputs disabled; VCC =5.5V 110 µA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 24-Pin Plastic DIP –40°C to +85°C 74ABT2952 N 74ABT2952 N SOT222-1 24-Pin plastic SO –40°C to +85°C 74ABT2952 D 74ABT2952 D SOT137-1 24-Pin Plastic SSOP Type II –40°C to +85°C 74ABT2952 DB 74ABT2952 DB SOT340-1 24-Pin Plastic TSSOP Type I –40°C to +85°C 74ABT2952 PW 7ABT2952PW DH SOT355-1 PIN CONFIGURATION PIN DESCRIPTION B7 1 24 VCC B6 2 23 A7 B5 3 22 A6 B4 4 21 A5 B3 5 20 A4 B2 6 19 A3 B1 7 18 A2 B0 8 17 A1 OEAB 9 16 A0 CPAB 10 15 OEBA CEAB 11 14 CPBA 13 CEBA GND 12 SA00114 1998 Feb 11 2 PIN NUMBER SYMBOL NAME AND FUNCTION 10, 14 CPAB / CPBA Clock input A to B / Clock input B to A 11, 13 CEAB / CEBA Clock enable input A to B / Clock enable input B to A 16, 17, 18, 19, 20, 21, 22, 23 A0 – A7 Data inputs/outputs (A side) 1, 2, 3, 4, 5, 6, 7, 8 B0 – B7 Data outputs/outputs (B side) 9, 15 OEAB / OEBA Output enable inputs 12 GND Ground (0V) 24 VCC Positive supply voltage 853-1554 18949 Philips Semiconductors Product specification Octal registered transceiver (3-State) 74ABT2952 LOGIC SYMBOL FUNCTION TABLE for Register An or Bn INPUTS 16 17 18 19 20 21 22 23 A0 A1 A2 A3 A4 A5 A6 A7 10 CPAB 11 CEAB OEBA 15 14 CPBA OEAB 9 13 CEBA 7 6 5 4 3 2 CPXX CEXX INTERNAL Q X X H NC Hold data L H ↑ ↑ L L L H Load data 1 FUNCTION TABLE for Output Enable SA00115 INPUTS LOGIC SYMBOL (IEEE/IEC) 11 EN1 13 EN2 15 EN3 9 EN4 10 C5 14 C6 16 2, 3, 6 OPERATING MODE H = High voltage level L = Low voltage level ↑ = Low–to–High transition X = Don’t care XX = AB or BA NC= No change B0 B1 B2 B3 B4 B5 B6 B7 8 An or Bn OEXX INTERNAL Q An or Bn 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 1, 4, 5 8 17 7 18 6 19 5 20 4 21 3 22 2 1 23 SA00116 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 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. Stresses beyond those listed 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. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 1998 Feb 11 3 Philips Semiconductors Product specification Octal registered transceiver (3-State) 74ABT2952 LOGIC DIAGRAM CEAB CPAB OEAB 11 10 9 DETAIL A CE A0 Q 16 D CP Q CE 8 D B0 CP A1 A2 A3 A4 A5 A6 A7 CEBA CPBA OEBA 17 7 18 6 19 5 20 4 DETAIL A X 7 21 3 22 2 23 1 B1 B2 B3 B4 B5 B6 B7 13 14 15 SA00117 RECOMMENDED OPERATING CONDITIONS LIMITS SYMBOL VCC PARAMETER UNIT DC supply voltage Min Max 4.5 5.5 V 0 VCC V VI Input voltage VIH High-level input voltage VIL Low-level Input voltage 0.8 V IOH High-level output current –32 mA IOL Low-level output current 64 mA 0 10 ns/V –40 +85 °C ∆t/∆v Input transition rise or fall rate Tamb Operating free-air temperature range 1998 Feb 11 2.0 4 V Philips Semiconductors Product specification Octal registered transceiver (3-State) 74ABT2952 DC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITIONS Min VIK VOH Input clamp voltage High-level output voltage Tamb = –40°C to +85°C Tamb = +25°C VCC = 4.5V; IIK = –18mA Typ Max –0.9 –1.2 Min UNIT Max –1.2 V VCC = 4.5V; IOH = –3mA; VI = VIL or VIH 2.5 3.5 2.5 V VCC = 5.0V; IOH = –3mA; VI = VIL or VIH 3.0 4.0 3.0 V VCC = 4.5V; IOH = –32mA; VI = VIL or VIH 2.0 2.6 2.0 V VOL Low-level output voltage VCC = 4.5V; IOL = 64mA; VI = VIL or VIH 0.42 0.55 0.55 V VRST Power-up output low voltage3 VCC = 5.5V; IO = 1mA; VI = GND or VCC 0.13 0.55 0.55 V Input leakage Control pins VCC = 5.5V; VI = GND or 5.5V ±0.01 ±1.0 ±1.0 µA current Data pins VCC = 5.5V; VI = GND or 5.5V 5 100 100 µA II Power-off leakage current VCC = 0.0V; VO = 4.5V; VI = 0.0V or 5.5V ±5.0 ±100 ±100 µA Power-up/down 3-State output current4 VCC = 2.1V; VO = 0.5V; VI = GND or VCC; VOE = Don’t care ±5.0 ±50 ±50 µA IOZH 3-State output High current VCC = 5.5V; VO = 2.7V; VI = VIL or VIH 5.0 50 50 µA IOZL 3-State output Low current VCC = 5.5V; VO = 0.5V; VI = VIL or VIH –5.0 –50 –50 µA ICEX Output High leakage current VCC = 5.5V; VO = 5.5V; VI = GND or VCC 5.0 50 50 µA –80 –180 –180 mA VCC = 5.5V; Outputs High, VI = GND or VCC 110 250 250 µA VCC = 5.5V; Outputs Low, VI = GND or VCC 20 30 30 mA VCC = 5.5V; Outputs 3-State; VI = GND or VCC 110 250 250 µA VCC = 5.5V; one input at 3.4V, other inputs at VCC or GND 0.3 1.5 1.5 mA IOFF IPU/IPD IO Output current1 ICCH ICCL Quiescent supply current ICCZ ∆ICC Additional supply current per input pin2 VCC = 5.5V; VO = 2.5V –50 –50 NOTES: 1.
