INTEGRATED CIRCUITS 74LVT623 3.3 V octal transceiver with dual enable (3-State) Product specification Supersedes data of 1996 Feb 15 IC24 Data Handbook 1999 Jul 09 Philips Semiconductors Product specification 3.3 V octal transceiver with dual enable (3-State) FEATURES 74LVT623 DESCRIPTION • Separate controls for data flow in each direction • Output capability: +64 mA/–32 mA • TTL input and output switching levels • Input and output interface capability to systems at 5 V supply • Bus-hold data inputs eliminate the need for external pull-up The 74LVT623 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. The 74LVT623 device is an octal transceiver featuring non–inverting 3-State bus compatible outputs in both send and receive directions. The 74LVT623 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. resistors to hold unused inputs • Live insertion/extraction permitted • No bus current loading when output is tied to 5 V bus • Power-up 3-State • Power-up reset • Latch-up protection exceeds 500 mA per JEDEC Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 Control of data flow from B to A is similar, but using the EBA, LEBA, and OEBA inputs. and 200 V per Machine Model QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER tPLH tPHL Propagation delay An to Bn or Bn to An CL = 50pF; VCC = 3.3 V CIN Input capacitance VI = 0 V or 3.0 V CI/O I/O capacitance Outputs disabled; VI/O = 0 V or 3.0 V ICCZ Total supply current Outputs disabled; VCC = 3.6 V TYPICAL UNIT 2.3 2.5 ns 4 pF 7 pF 0.13 mA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 24-Pin Plastic SOL –40°C to +85°C 74LVT623 D 74LVT623 D SOT137-1 24-Pin Plastic SSOP Type II –40°C to +85°C 74LVT623 DB 74LVT623 DB SOT340-1 24-Pin Plastic TSSOP Type I –40°C to +85°C 74LVT623 PW 74LVT623PW DH SOT355-1 PIN CONFIGURATION LOGIC SYMBOL OEAB A0 OEAB 1 20 VCC A0 2 19 OEBA A1 3 18 B0 A2 4 17 B1 A3 5 16 B2 A4 6 15 B3 A1 7 14 8 13 B5 A7 9 12 B6 GND 10 11 OEBA 2 18 A2 A5 A6 B7 A7 1999 Jul 09 B1 5 15 B3 6 14 B4 7 13 B5 8 12 B6 9 11 SA00189 B1 4 16 A3 B0 3 B4 A6 19 17 A4 A5 1 B7 SA00195 2 853–2164 21957 Philips Semiconductors Product specification 3.3 V octal transceiver with dual enable (3-State) LOGIC SYMBOL (IEEE/IEC) 1 EN1 19 EN1 2 74LVT623 PIN DESCRIPTION PIN NUMBER SYMBOL 1 OEAB 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) 17 19 OEBA Output enable input, B side to A side (active-Low) 16 10 GND Ground (0 V) 15 20 VCC Positive supply voltage 18 1 2 3 4 5 6 14 7 13 8 12 9 11 NAME AND FUNCTION Output enable input, A side to B side (active-High) FUNCTION TABLE INPUTS SA00196 INPUTS/OUTPUTS OEBA OEAB An Bn L L An = Bn Inputs H H Inputs Bn = An H L Z Z L H An = Bn Bn = An H = High voltage level L = Low voltage level Z = High impedance “off” state ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC PARAMETER IIK DC input diode current VI DC input voltage3 IOK DC output diode current VOUT IOUT O CONDITIONS DC supply voltage DC output voltage3 DC output current VI < 0 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 128 Output in High state –64 mA Tstg Storage temperature range –65 to 150 °C NOTES: 1. Stresses beyond those listed may cause permanent damage to the device.

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 1999 Jul 09 3 Philips Semiconductors Product specification 3.3 V octal transceiver with dual enable (3-State) 74LVT623 RECOMMENDED OPERATING CONDITIONS SYMBOL VCC LIMITS PARAMETER DC supply voltage UNIT MIN MAX 2.7 3.6 V 0 5.5 V VI Input voltage VIH High-level input voltage VIL Low-level input voltage 0.8 V IOH High-level output current –32 mA Low-level output current 32 Low-level output current; current duty cycle ≤ 50%; f ≥ 1 kHz 64 IOL O 2.0 ∆t/∆v Input transition rise or fall rate; outputs enabled Tamb Operating free-air temperature range V –40 mA 10 ns/V +85 °C DC ELECTRICAL CHARACTERISTICS LIMITS SYMBOL VIK PARAMETER Input clamp voltage TEST CONDITIONS Temp = -40°C to +85°C MIN TYP1 MAX –0.9 –1.2 VCC-0.2 VCC-0.1 VCC = 2.7 V; IOH = –8 mA 2.4 2.5 VCC = 3.0 V; IOH = –32 mA 2.0 2.2 VCC = 2.7 V; IIK = –18 mA VCC = 2.7 to 3.6 V; IOH = –100 µA VOH VOL VRST High-level output voltage Low-level output voltage Power-up output low voltage5 0.1 0.2 VCC = 2.7 V; IOL = 24 mA 0.3 0.5 VCC = 3.0 V; IOL = 16 mA 0.25 0.4 VCC = 3.0 V; IOL = 32 mA 0.3 0.5 VCC = 3.0 V; IOL = 64 mA 0.4 0.55 VCC = 3.6 V; IO = 1 mA; VI = GND or VCC 0.13 0.55 VCC = 3.6 V; VI = VCC or GND ±0.1 ±1 1 10 1 20 0.1 1 Control pins II Input leakage current VCC = 3.6 V; VI = 5.5 V I/O Data pins4 VCC = 3.6 V; VI = VCC IOFF IHOLD O IEX IPU/PD VCC = 3.6 V; VI = 0 –1 -5 Output off current VCC = 0 V; VI or VO = 0 to 4.5 V 1 ±100 Bus Hold current A or B ports VCC = 3 V; VI = 0.8 V 75 150 VCC = 3 V; VI = 2.0 V –75 –150 V µA µA µA VO = 5.5 V; VCC = 3.0 V 60 125 µA Power up/down 3-State output current3 VCC ≤ 1.2 V; VO = 0.5 V to VCC; VI = GND or VCC; OE/OE = Don’t care 15 ±100 µA VCC = 3.6 V; Outputs High, VI = GND or VCC, IO = 0 0.13 0.19 VCC = 3.6 V; Outputs Low, VI = GND or VCC, IO = 0 3 12 VCC = 3.6 V; Outputs Disabled; VI = GND or VCC, IO = 0 0.13 0.19 VCC = 3 V to 3.6 V; One input at VCC -0.6 V, Other inputs at VCC or GND 0.1 0.2 Quiescent supply current ICCZ ∆ICC V Current into an output in the High state when VO > VCC ICCH ICCL V V VCC = 2.7 V; IOL = 100 µA VCC = 0 or 3.6 V; VI = 5.5 V UNIT Additional supply current per input pin2 mA mA NOTES: 1.
