INTEGRATED CIRCUITS 74ABT16245B 74ABTH16245B 16-bit bus transceiver (3-state) Product specification Supersedes data of 1996 Nov 20 IC23 Data Handbook 1998 Feb 25 Philips Semiconductors Product specification 74ABT16245B 74ABTH16245B 16-bit bus transceiver (3-State) FEATURES DESCRIPTION • 16-bit bidirectional bus interface • Power-up 3-State • Multiple VCC and GND pins minimize switching noise • 3-State buffers • Output capability: +64 mA/–32mA • Latch–up protection exceeds 500mA per JEDEC Std 17 • Live insertion/extraction permitted • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 The 74ABT16245B high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT16245B device is a dual octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features two Output Enable (1OE, 2OE) inputs for easy cascading and two Direction (1DIR, 2DIR) inputs for direction control. Two options are available, 74ABT16245B which does not have the bus hold feature and the 74ABTH16245B which incorporates the bus hold feature. and 200V per Machine Model • 74ABTH16245B 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 tPLH tPHL Propagation delay nAx to nBx or nBx to nAx CL = 50pF; VCC = 5V CIN Input capacitance VI = 0V or VCC CI/O I/O pin capacitance VO = 0V or VCC; 3-State ICCZ Quiescent su supply ly current ICCL TYPICAL UNIT 2.0 2.3 ns 4 pF 7 pF Outputs disabled; VCC =5.5V 500 µA Output Low; VCC =5.5V 10 mA ORDERING INFORMATION TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 48-Pin Plastic SSOP Type III PACKAGES –40°C to +85°C 74ABT16245B DL BT16245B DL SOT370-1 48-Pin Plastic TSSOP Type II –40°C to +85°C 74ABT16245B DGG BT16245B DGG SOT362-1 48-Pin Plastic SSOP Type III –40°C to +85°C 74ABTH16245B DL BH16245B DL SOT370-1 48-Pin Plastic TSSOP Type II –40°C to +85°C 74ABTH16245B DGG BH16245B DGG SOT362-1 1998 Feb 25 2 853-1742 19018 Philips Semiconductors Product specification 74ABT16245B 74ABTH16245B 16-bit bus transceiver (3-State) PIN CONFIGURATION PIN DESCRIPTION 1DIR 1 48 1OE 1B0 2 47 1A0 1B1 3 46 1A1 GND 4 45 GND 1B2 5 44 1A2 1B3 6 43 1A3 VCC 7 42 VCC 1B4 8 41 1A4 1B5 9 40 1A5 GND 10 39 GND 1B6 11 38 1A6 1B7 12 37 1A7 2B0 13 36 2A0 2B1 14 35 2A1 GND 15 34 GND 2B2 16 33 2A2 2B3 17 32 2A3 VCC 18 31 VCC 2B4 19 30 2A4 2B5 20 29 2A5 21 28 GND GND 2B6 22 27 2A6 2B7 23 26 2A7 2DIR 24 25 SYMBOL PIN NUMBER 1DIR, 2DIR 1, 24 NAME AND FUNCTION Direction control inputs (Active-High) 1A0 – 1A7, 2A0 – 2A7 47, 46, 44, 43 41, 40, 38, 37 Data inputs/outputs (A side) 36, 35, 33, 32 30, 29, 27, 26 1B0 – 1B7 2B0 – 2B7 2, 3, 5, 6 8, 9, 11, 12 Data inputs/outputs (B side) 13, 14, 16, 17 19, 20, 22, 23 1OE, 2OE 48, 25 Output enables GND 4, 10, 15, 21 Ground (0V) 28, 34, 39, 45 VCC 7, 18, 31, 42 Positive supply voltage LOGIC SYMBOL (IEEE/IEC) 1OE 48 1DIR 1 2OE 25 G6 2DIR 24 6 EN4 (BA) G3 3 EN1 (BA) 3 EN2 (AB) 2OE SA00020 6 EN5 (AB) LOGIC SYMBOL 1DIR 1A0 1 2DIR 48 1A0 47 2 36 13 1A1 2OE 1A2 2B0 1A3 1A4 1A1 1A2 46 44 3 5 1B1 1B2 2A1 2A2 35 33 14 16 2B1 1A5 1A6 2B2 1A7 1A3 43 6 1B3 2A3 32 2 1B0 2∇ 25 2A0 ∇1 24 1OE 1B0 47 17 2A0 2B3 46 3 44 5 43 6 41 8 40 9 38 11 37 12 36 ∇4 13 1B1 1B2 1B3 1B4 1B5 1B6 1B7 2B0 5∇ 1A4 41 8 1B4 2A4 30 19 2A1 2B4 2A2 1A5 40 9 1B5 2A5 29 20 2B5 2A3 2A4 1A6 1A7 38 37 11 12 1B6 1B7 2A6 2A7 27 26 22 23 2B6 2A5 2A6 2B7 2A7 35 14 33 16 32 17 30 19 29 20 27 22 26 23 2B1 2B2 2B3 2B4 2B5 2B6 2B7 SA00022 SA00021 1998 Feb 25 3 Philips Semiconductors Product specification 74ABT16245B 74ABTH16245B 16-bit bus transceiver (3-State) FUNCTION TABLE INPUTS H L X Z INPUTS/OUTPUTS nOE nDIR nAx nBx L L A=B Inputs L H Inputs B=A H X Z Z = High voltage level = Low voltage level = Don’t care = High impedance “off” scale 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 output in High state –64 DC supply voltage IIK DC input diode current VI DC input voltage3 IOK DC output diode current VOUT DC output voltage3 IOUT O DC output current Tstg Storage temperature range VI < 0 mA –65 to 150 °C 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.
