The 74ABT16244A 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. Two options are available, 74ABT16244A which does not have the bus hold feature and 74ABTH16244A which incorporates the bus hold feature. and 200 V per Machine Model • 74ABTH16244A incorporates bus hold data inputs which eliminate the need for external pull up resistors to hold unused inputs • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25°C; GND = 0V PARAMETER TYPICAL UNIT 1.7 2.1 ns pF tPLH tPHL Propagation delay nAx to nYx CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC 4 Output capacitance VO = 0V or VCC; 3-State 7 pF Outputs disabled; VCC = 5.5V 450 µA Outputs low; VCC = 5.5V 10 mA COUT ICCZ Quiescent su supply ly current ICCL ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 48-Pin Plastic SSOP Type III –40°C to +85°C 74ABT16244A DL BT16244A DL SOT370-1 48-Pin Plastic TSSOP Type II –40°C to +85°C 74ABT16244A DGG BT16244A DGG SOT362-1 48-Pin Plastic SSOP Type III –40°C to +85°C 74ABH16244A DL BH16244A DL SOT370-1 48-Pin Plastic TSSOP Type II –40°C to +85°C 74ABH16244A DGG BH16244A DGG SOT362-1 LOGIC SYMBOL 47 46 44 43 1 41 40 38 37 48 1A0 1Y0 1A1 1Y1 1A2 1Y2 1A3 1Y3 2 36 3 35 5 33 6 32 1OE 2A0 25 2Y0 2A1 2Y1 2A2 2Y2 2A3 2Y3 2OE 8 30 9 29 11 27 12 26 24 3A0 3Y0 3A1 3Y1 3A2 3Y2 3A3 3Y3 13 14 16 17 3OE 4A0 4Y0 4A1 4Y1 4A2 4Y2 4A3 4Y3 19 20 22 23 4OE SA00014 1998 Oct 07 2 853-1769 20143 Philips Semiconductors Product specification 74ABT16244A 74ABTH16244A 16-bit buffer/line driver (3-State) LOGIC SYMBOL (IEEE/IEC) 1OE 1 EN1 2OE 48 EN2 3OE 25 EN3 4OE 24 EN4 1A0 1A1 1A2 1A3 2A0 2A1 2A2 2A3 3A0 3A1 3A2 3A3 4A0 4A1 4A2 4A3 47 PIN DESCRIPTION 2 1Y0 46 3 1Y1 44 5 1Y2 43 6 1Y3 8 2Y0 1 41 1 1∇ 2∇ 40 9 38 11 2Y2 37 12 2Y3 36 2Y1 13 3Y0 35 14 3Y1 33 16 3Y2 32 17 3Y3 19 4Y0 20 4Y1 1 30 1 3∇ 4∇ 29 27 22 26 23 1 48 2OE 2 47 1A0 1Y1 3 46 1A1 GND 4 45 GND 1Y2 5 44 1A2 1Y3 6 43 1A3 VCC 7 42 VCC 2Y0 8 41 2A0 2Y1 9 40 2A1 GND 10 39 GND 2Y2 11 38 2A2 2Y3 12 37 2A3 3Y0 13 36 3A0 3Y1 14 35 3A1 GND 15 34 GND 3Y2 16 33 3A2 3Y4 17 32 3A3 VCC 18 31 VCC 4Y0 19 30 4A0 4Y1 20 29 4A1 GND 21 28 GND 4Y2 22 27 4A2 4Y3 23 26 4A3 4OE 24 25 3OE 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 Output enables 4, 10, 15, 21 28, 34, 39, 45 GND Ground (0V) 7, 18, 31, 42 VCC Positive supply voltage nOE NAME AND FUNCTION OUTPUTS nAx nYx L L L 4Y2 L H H 4Y3 H X Z H L X Z SA00013 1998 Oct 07 1A0 – 1A3, 2A0 – 2A3, 3A0 – 3A3, 4A0 – 4A3 INPUTS PIN CONFIGURATION 1Y0 SYMBOL 47, 46, 44, 43 41, 40, 38, 37 36, 35, 33, 32 30, 29, 27, 26 FUNCTION TABLE SH00088 1OE PIN NUMBER 3 = High voltage level = Low voltage level = Don’t care = High impedance “off” state Philips Semiconductors Product specification 74ABT16244A 74ABTH16244A 16-bit buffer/line driver (3-State) ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK 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 output in High state –64 DC supply voltage DC input diode current VI < 0 voltage3 VI DC input IOK DC output diode current voltage3 VOUT DC output IOUT O DC output current Tstg Storage temperature range mA °C –65 to 150 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.
