INTEGRATED CIRCUITS 74ABT620 Octal transceiver with dual enable, inverting (3-State) Product specification IC23 Data Handbook 1993 Jun 21 Philips Semiconductors Product specification Octal transceiver with dual enable, inverting (3-State) FEATURES 74ABT620 DESCRIPTION • Octal bidirectional bus interface • 3-State buffers • Power-up 3-State • Live insertion/extraction permitted • Output capability: +64mA/–32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 The 74ABT620 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT620 device is an octal transceiver featuring inverting 3-State bus compatible outputs in both send and receive directions. The 74ABT620 is designed for asynchronous two-way communication between data buses. The control function implementation allows for maximum flexibility in timing. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic levels at the Enable inputs (OEBA and OEAB). The Enable inputs can be used to disable the device so that the buses are effectively isolated. and 200 V per Machine Model QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 3.1 ns tPLH tPHL Propagation delay An to Bn or Bn to An CL = 50pF; VCC = 5V CIN Input capacitance OEAB, OEBA 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 50 µA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 20-Pin Plastic DIP –40°C to +85°C 74ABT620 N 74ABT620 N SOT146-1 20-Pin plastic SO –40°C to +85°C 74ABT620 D 74ABT620 D SOT163-1 20-Pin Plastic SSOP Type II –40°C to +85°C 74ABT620 DB 74ABT620 DB SOT339-1 20-Pin Plastic TSSOP Type I –40°C to +85°C 74ABT620 PW 74ABT620PW DH SOT360-1 PIN CONFIGURATION PIN DESCRIPTION OEAB 1 20 VCC A0 2 19 OEBA A1 3 18 B0 A2 4 17 B1 A3 5 16 B2 A4 6 15 B3 A5 7 14 B4 A6 8 13 B5 A7 9 12 B6 11 B7 GND 10 PIN NUMBER SYMBOL NAME AND FUNCTION 1 OEAB Output enable input, A side to B side (active-High) 2, 3, 4, 5, 6, 7, 8, 9 A0 – A7 Data inputs/outputs (A side) 18, 17, 16, 15, 14, 13, 12, 11 B0 – B7 Data inputs/outputs (B side) 19 OEBA Output enable input, B side to A side (active-Low) 10 GND Ground (0V) 20 VCC Positive supply voltage SA00189 1993 Jun 21 2 853–1611 10081 Philips Semiconductors Product specification Octal transceiver with dual enable, inverting (3-State) LOGIC SYMBOL 74ABT620 LOGIC SYMBOL (IEEE/IEC) 19 1 OEBA OEAB 1 EN1 19 EN1 2 1 2 A0 18 B0 3 A1 17 B1 4 A2 18 2 16 B2 5 15 16 4 B3 6 17 3 A3 A4 15 5 14 B4 7 14 6 A5 13 B5 8 13 7 A6 12 8 12 B6 9 11 9 A7 11 B7 SA00191 SA00190 FUNCTION TABLE INPUTS INPUTS/OUTPUTS OEBA OEAB An Bn L L Bn Inputs H H Inputs An H L Z Z L H Bn Inputs or Inputs An H = High voltage level L = Low voltage level Z = High impedance ”off” state ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC IIK PARAMETER 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. 1993 Jun 21 3 Philips Semiconductors Product specification Octal transceiver with dual enable, inverting (3-State) 74ABT620 RECOMMENDED OPERATING CONDITIONS SYMBOL VCC PARAMETER LIMITS DC supply voltage UNIT 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 5 ns/V –40 +85 °C 2.0 ∆t/∆v Input transition rise or fall rate Tamb Operating free-air temperature range V DC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL PARAMETER TEST CONDITIONS Min VIK VOH VOL II 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 2.9 2.5 V VCC = 5.0V; IOH = –3mA; VI = VIL or VIH 3.0 3.4 3.0 V VCC = 4.5V; IOH = –32mA; VI = VIL or VIH 2.0 2.4 2.0 V Low-level output voltage VCC = 4.5V; IOL = 64mA; VI = VIL or VIH 0.42 Input leakage Control pins VCC = 5.5V; VI = GND or 5.5V ±0.01 current Data pins VCC = 5.5V; VI = GND or 5.5V ±5 0.55 0.55 V ±1.0 ±1.0 µA ±100 ±100 µA Power-off leakage current VCC = 0.0V; VO or VI ≤ 4.5V ±5.0 ±100 ±100 µA Power-up/down 3-State output current3 VCC = 2.1V; VO = 0.5V; VI = GND or VCC; VOE and V OE = Don’t care ±5.0 ±50 ±50 µA IIH + IOZH 3-State output High current VCC = 5.5V; VO = 2.7V; VI = VIL or VIH 5.0 50 50 µA IIL + IOZL 3-State output Low current VCC = 5.5V; VO = 0.5V; VI = VIL or VIH –5.0 –50 –50 µA Output High leakage current VCC = 5.5V; VO = 5.5V; VI = GND or VCC 5.0 50 50 µA –100 –180 –180 mA VCC = 5.5V; Outputs High, VI = GND or VCC 50 250 250 µA VCC = 5.5V; Outputs Low, VI = GND or VCC 24 30 30 mA VCC = 5.5V; Outputs 3-State; VI = GND or VCC 50 250 250 µA VCC = 5.5V; one input at 3.4V, other inputs at VCC or GND 0.05 1.5 1.5 mA IOFF IPU/IPD ICEX 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.
