INTEGRATED CIRCUITS 74ABT2245 Octal transceiver with direction pin and 30 series termination resistors (3-State) Product data 2002 Dec 17 Supersedes data of 1998 Jan 16 Philips Semiconductors Product data Octal transceiver with direction pin and 74ABT2245 30 series termination resistors (3-State) FEATURES DESCRIPTION The 74ABT2245 high-performance BiCMOS device combines low Octal bidirectional bus interface static and dynamic power dissipation with high speed. 3-State buffers The 74ABT2245 device is an octal transceiver featuring Output capability: +12 mA / 32 mA non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes Latch-up protection exceeds 500 mA per Jedec Std 17 external timing requirements. The device features an Output Enable (OE) input for easy cascading and a Direction (DIR) input for ESD protection exceeds 2000 V per MIL STD 833 Method 3015 direction control. and 200 V per Machine Model The 74ABT2245 is designed with 30 series resistance in both the Power-up 3-State HIGH and LOW states of the output. This design reduces line noise Live insertion/extraction permitted in applications such as memory address drivers, clock drivers, and bus receivers/transmitters. Same as 74ABT245-1 The 74ABT2245 is the same as the 74ABT245-1. The part number Outputs include series resistance of 30 , making external has been changed to reflect industry standards. termination resistors unnecessary Inputs are disabled during 3-State mode QUICK REFERENCE DATA CONDITIONS SYMBOL PARAMETER TYPICAL UNIT T = 25 C GND = 0 V amb t Propagation delay PLH C = 50 pF V = 5 V 3.9 ns L CC t An to Bn or Bn to An PHL C Input capacitance DIR, OE V = 0 V or V 4 pF IN I CC C I/O pin capacitance Outputs disabled V = 0 V or V 7 pF I/O O CC I Total supply current Outputs disabled V = 5.5 V 50 A CCZ CC ORDERING INFORMATION PACKAGES TEMPERATURE RANGE PART NUMBER DWG NUMBER 20-Pin plastic SO 40 C to +85 C 74ABT2245D SOT163-1 20-Pin Plastic SSOP Type II 40 C to +85 C 74ABT2245DB SOT339-1 20-Pin Plastic TSSOP Type I 40 C to +85 C 74ABT2245PW SOT360-1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER SYMBOL NAME AND FUNCTION DIR 1 20 V CC 1 DIR Direction control input A0 2 19 OE 2, 3, 4, 5, 6, 7, 8, 9 A0 A7 Data inputs/outputs (A side) A1 3 18 B0 A2 4 17 B1 18, 17, 16, 15, 14, B0 B7 Data inputs/outputs (B side) 13, 12, 11 A3 5 16 B2 A4 6 15 B3 Output enable input 19 OE (active-LOW) A5 7 14 B4 A6 8 13 B5 10 GND Ground (0 V) A7 9 12 B6 20 V Positive supply voltage CC GND 10 11 B7 SA00121 2 2002 Dec 17
