The MB2541 has two 8-bit buffers that are ideal for driving bus lines. The outputs are all capable of sinking 64mA and sourcing 32mA. Microprocessors • 3-State buffers sink 64mA and source 32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model • Inputs are disabled during 3-State mode QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 3.0 3.1 ns tPLH tPHL Propagation delay nIx to nYx CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC 4 pF COUT Output capacitance VO = 0V or VCC; 3-State 7 pF ICCZ Total supply current Outputs disabled; VCC =5.5V 65 µA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER –40°C to +85°C MB2541 BB MB2541 BB SOT379-1 52–pin plastic Quad Flat Pack 52 51 50 49 48 47 46 45 44 43 42 1A3 1A2 GND 1A1 1A0 1OE1 GND PIN DESCRIPTION 1OE0 1Y0 1Y1 GND 1Y2 1Y3 PIN CONFIGURATION 41 40 VCC 1 39 V CC 1Y4 2 38 1A4 1Y5 3 37 1A5 GND 4 36 GND 1Y6 5 35 1A6 1Y7 6 34 1A7 52–pin PQFP GND 7 2Y0 8 32 2A0 2Y1 9 31 2A1 SYMBOL 44, 43, 41, 40, 38, 37, 35, 34, 32, 31, 29, 28, 26, 25, 23, 22 1A0 – 1A7 2A0 – 2A7 Data inputs 48, 49, 51, 52, 2, 3, 5, 6, 8, 9, 11, 12, 14, 15, 17, 18 1Y0 – 1Y7, 2Y0 – 2Y7 Data outputs 47, 45, 19, 21 1OE0, 1OE1, 2OE0, 2OE1 4, 7, 10, 16, 20, 24, 30, 33, 36, 42, 46, 50 GND Ground (0V) 1, 13, 27, 39 VCC Positive supply voltage 33 GND GND 10 30 GND 2Y2 11 29 2A2 2Y3 12 28 2A3 NAME AND FUNCTION Output enables 27 V CC 2A4 2A5 GND 2A6 26 2A7 21 22 23 24 25 2OE1 GND 2OE0 2Y7 GND 17 18 19 20 2Y5 14 15 16 2Y6 13 2Y4 VCC PIN NUMBER SB00082 1998 Jan 16 2 853–1574 18869 Philips Semiconductors Product specification 16-bit buffer/line drivers (3-State) MB2541 LOGIC SYMBOL 1OE0 1OE1 LOGIC SYMBOL (IEEE/IEC) 47 2OE0 45 2OE1 19 21 47 45 1A0 1A1 1A2 1A3 1A4 1A5 1A6 1A7 44 48 43 49 51 41 52 40 2 38 3 37 5 35 6 34 1Y0 2A0 1Y1 2A1 1Y2 2A2 1Y3 2A3 1Y4 2A4 1Y5 2A5 1Y6 2A6 1Y7 2A7 32 8 31 9 29 11 28 12 26 14 25 15 23 17 22 18 19 & EN 21 & EN 2Y0 2Y1 2Y2 44 48 32 43 49 31 9 41 51 29 11 40 52 28 12 38 2 26 14 37 3 25 15 35 5 23 17 34 6 22 18 8 2Y3 2Y4 2Y5 2Y6 2Y7 SB00084 SB00083 FUNCTION TABLE INPUTS OUTPUTS nOE0 nOE1 nIx nYx L L L L L L H H X H X Z H X X Z ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC 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 IIK DC input diode current VI DC input voltage3 IOK DC output diode current voltage3 VOUT DC output IOUT DC output current Tstg Storage temperature range VI < 0 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 Jan 16 3 Philips Semiconductors Product specification 16-bit buffer/line drivers (3-State) MB2541 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 10 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 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 0.55 0.55 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; VO or VI ≤ 4.5V ±5.0 ±100 ±100 µA Power-up/down 3-State output current VCC = 2.0V; VO = 0.5V; VI = GND or VCC; VOE = VCC ±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 –70 –180 –180 mA VCC = 5.5V; Outputs High, VI = GND or VCC 65 250 250 µA VCC = 5.5V; Outputs Low, VI = GND or VCC 48 60 60 mA VCC = 5.5V; Outputs 3-State; VI = GND or VCC 65 250 250 µA Outputs enabled, one input at 3.4V, other inputs at VCC or GND; VCC = 5.5V 0.5 1.5 1.5 mA 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: 1.
