INTEGRATED CIRCUITS 74ABT2241 Octal buffer with 30 series termination resistors; (3-State) Product specification IC23 Data Handbook 1996 Sep 30 Philips Semiconductors Product specification Octal buffer with 30 series termination resistors (3-State) FEATURES 74ABT2241 DESCRIPTION • Octal bus interface • 3-State buffers • Power-up 3-State • Output capability: +12mA/–32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 The 74ABT2241 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT2241 device is an octal buffer that is ideal for driving bus lines. The device features two Output Enables (1OE, 2OE), each controlling four of the 3-State outputs. The 74ABT2241 is designed with 30W series resistance in both the High and Low states of the output. The design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transceivers. and 200 V per Machine Model QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 2.9 ns tPLH tPHL Propagation delay An to Yn CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC 3 pF COUT Output 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 74ABT2241 N 74ABT2241 N SOT146-1 20-Pin plastic SO –40°C to +85°C 74ABT2241 D 74ABT2241 D SOT163-1 20-Pin Plastic SSOP Type II –40°C to +85°C 74ABT2241 DB 74ABT2241 DB SOT339-1 20-Pin Plastic TSSOP Type I –40°C to +85°C 74ABT2241 PW 7ABT2241PW DH SOT360-1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER SYMBOL NAME AND FUNCTION 2, 4, 6, 8 1A0 – 1A3 Data inputs 17, 15, 13, 11 2A0 – 2A3 Data inputs 18, 16, 14, 12 1Y0 – 1Y3 Data outputs 1OE 1 20 VCC 1A0 2 19 2OE 2Y0 3 18 1Y0 1A1 4 17 2A0 3, 5, 7, 9 2Y0 – 2Y3 Data outputs 2Y1 5 16 1Y1 1, 19 1OE, 2OE Output enables 1A2 6 15 2A1 10 GND Ground (0V) 2Y2 7 14 1Y2 1A3 8 13 2A2 20 VCC Positive supply voltage 2Y3 9 12 1Y3 11 2A3 GND 10 SA00038 1996 Sep 30 2 853–1879 17325 Philips Semiconductors Product specification Octal buffer with 30 series termination resistors (3-State) LOGIC SYMBOL (IEEE/IEC) 74ABT2241 LOGIC SYMBOL 2 1A0 1Y0 1A1 1Y1 1A2 1Y2 1A3 1Y3 18 1 EN 4 2 18 4 16 6 14 8 12 6 8 1 17 19 15 EN 17 3 15 5 13 7 11 9 13 11 19 16 14 12 1OE 2A0 2Y0 2A1 2Y1 2A2 2Y2 2A3 2Y3 3 5 7 9 2OE SA00039 SA00040 SCHEMATIC OF EACH OUTPUT FUNCTION TABLE INPUTS OUTPUTS VCC H L X Z OUTPUT 1OE 1An 2OE 2An 1Yn 2Yn L L H L L L L H H H H H H X L X Z Z = High voltage level = Low voltage level = Don’t care = High impedance ”off” state GND SA00409 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. 1996 Sep 30 3 Philips Semiconductors Product specification Octal buffer with 30 series termination resistors (3-State) 74ABT2241 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 12 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 Input clamp voltage High-level output voltage Low-level out output ut 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 VCC = 4.5V; IOL = 5mA; VI = VIL or VIH 0.32 VCC = 4.5V; IOL = 12mA; VI = VIL or VIH 0.55 0.55 V 0.8 0.8 V Input leakage current VCC = 5.5V; VI = GND or 5.5V ±0.01 ±1.0 ±1.0 µA Power-off leakage current VCC = 0.0V; VI or VO ≤ 4.5V ±5.0 ±100 ±100 µA Power-up/down 3-State output current3 VCC = 2.0V; VO = 0.5V; VI = GND or VCC; V OE = VCC; VOE = GND ±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 –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 Outputs enabled, one input at 3.4V, other inputs at VCC or GND; VCC = 5.5V 0.5 1.5 1.5 mA Outputs 3-State, one data input at 3.4V, other inputs at VCC or GND; VCC = 5.5V 50 250 250 µA Outputs 3-State, one enable input at 3.4V, other inputs at VCC or GND; VCC = 5.5V 0.5 1.5 1.5 mA II 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 NOTES: 1996 Sep 30 4 –50 Philips Semiconductors Product specification Octal buffer with 30 series termination resistors (3-State) 74ABT2241 1.
