This device is a 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-State outputs. The 74ALVT162241 is designed with 30 series resistance in both High and Low output stages. This design reduces the line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters. The series termination resistors reduce overshoot and undershoot and are ideal for driving memory arrays. resistors to hold unused inputs • Outputs include series resistance of 30 making external termination resistors unnecessary • Live insertion/extraction permitted • Power-up 3-State • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model QUICK REFERENCE DATA SYMBOL TYPICAL CONDITIONS Tamb = 25°C PARAMETER tPLH tPHL Propagation delay nAx to nYx CL = 50pF UNIT 2.5V 3.3V 3.1 2.3 2.2 2.0 ns pF CIN Input capacitance nOE VI = 0V or VCC 3 3 COut Output pin capacitance VI/O = 0V or VCC 9 9 pF ICCZ Total supply current Outputs disabled 40 70 µA ORDERING INFORMATION TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 48-Pin Plastic SSOP Type III PACKAGES –40°C to +85°C 74ALVT162241 DL AV162241 DL SOT370-1 48-Pin Plastic TSSOP Type II –40°C to +85°C 74ALVT162241 DGG AV162241 DGG SOT362-1 LOGIC SYMBOL 47 1A0 SCHEMATIC OF EACH OUTPUT 1Y0 2 36 3A0 3Y0 VCC 13 VCC 46 44 43 1 1A1 1Y1 1A2 1Y2 1A3 1Y3 3 35 5 33 6 1OE 32 25 3A1 3Y1 3A2 3Y2 3A3 3Y3 14 16 17 27Ω 3OE OUTPUT 27Ω 41 40 38 2A0 2Y0 2A1 2Y1 2A2 2Y2 2A3 2Y3 8 30 9 29 11 27 4A0 4Y0 4A1 4Y1 4A2 4Y2 4A3 4Y3 19 20 22 SW00007 37 48 2OE 12 26 24 23 4OE SA00405 1998 Feb 13 2 853-2042 18960 Philips Semiconductors Product specification 2.5V/3.3V 16-bit buffer/driver with 30 termination resistors (3-State) 74ALVT162241 PIN CONFIGURATION 1OE 1Y0 1Y1 GND 1Y2 1Y3 VCC 2Y0 2Y1 GND 2Y2 2Y3 3Y0 3Y1 GND 3Y2 3Y4 VCC 4Y0 4Y1 GND 4Y2 4Y3 4OE PIN DESCRIPTION 1 48 2 47 3 46 4 45 5 44 6 43 7 42 8 41 9 40 10 39 11 38 12 37 13 36 14 35 15 34 16 33 17 32 18 31 19 30 20 29 21 28 22 27 23 26 24 25 PIN NUMBER SYMBOL 47, 46, 44, 43, 41, 40, 38, 37, 36, 35, 33, 32, 30, 29, 27, 26 1A0-1A3 2A0-2A3 3A0-3A3 4A0-4A3 Data inputs 2, 3, 5, 6, 8, 9, 11, 12, 13, 14, 16, 17, 19, 20, 22, 23 1Y0-1Y3 2Y0-2Y3 3Y0-3Y3 4Y0-4Y3 Data outputs 1, 48, 25, 24 1OE, 2OE, 3OE, 4OE GND 4, 10, 15, 21, 28, 34, 39, 45 GND Ground (0V) 2A2 7, 18, 31, 42 VCC Positive supply voltage 2OE 1A0 1A1 GND 1A2 1A3 VCC 2A0 2A1 3A0 FUNCTION TABLE 3A1 GND 3A2 3A3 VCC 4A0 EN1 2OE 48 EN2 3OE 25 EN3 4OE 24 EN4 1A1 1A2 1A3 1A4 2A1 2A2 2A3 2A4 3A1 3A2 3A3 3A4 4A1 4A2 4A3 4A4 47 GND 4A2 4A3 3OE 2 1Y1 3 1Y2 44 5 1Y3 43 6 1Y4 8 2Y1 41 1 1∇ 2∇ 40 9 38 11 2Y3 37 12 2Y4 13 3Y1 35 14 3Y2 33 16 3Y3 32 17 3Y4 19 4Y1 29 20 4Y2 27 22 4Y3 26 23 36 30 1 1 3∇ 4∇ 2Y2 4Y4 SA00406 1998 Feb 13 Outputs 1Yx, 4Yx H L Z Inputs 2OE, 3OE 2Ax, 3Ax H H H L L X Outputs 2Yx, 3Yx H L Z H = High voltage level L = Low voltage level X = Don’t care Z = High Impedance “off ” state 46 1 Inputs 1OE, 4OE 1Ax, 4Ax L H L L H X 4A1 LOGIC SYMBOL (IEEE/IEC) 1 Output enables 2A3 SA00407 1OE NAME AND FUNCTION 3 Philips Semiconductors Product specification 2.5V/3.3V 16-bit buffer/driver with 30 termination resistors (3-State) 74ALVT162241 ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK DC input diode current VI DC input voltage3 IOK DC output diode current VOUT CONDITIONS RATING DC supply voltage V -50 mA VI < 0 DC output voltage3 IOUT DC output out ut current Tstg Storage temperature range UNIT -0.5 to +4.6 -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 °C -65 to +150 NOTES: 1.
