INTEGRATED CIRCUITS 74ABT245 Octal transceiver with direction pin (3-State) Product data 2003 Feb 06 Supersedes data of 1998 Jan 16 Philips Semiconductors Product data Octal transceiver with direction pin (3-State) 74ABT245 FEATURES DESCRIPTION The 74ABT245 high-performance BiCMOS device combines low Octal bidirectional bus interface static and dynamic power dissipation with high speed and high 3-State buffers output drive. Output capability: +64 mA/32 mA The 74ABT245 device is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. Latch-up protection exceeds 500 mA per Jedec Std 17 The control function implementation minimizes external timing requirements. The device features an Output Enable (OE) input for ESD protection exceeds 2000 V per MIL STD 833 Method 3015 easy cascading and a Direction (DIR) input for direction control. and 200 V per Machine Model Power-up 3-State Live insertion/extraction permitted 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 2.2 PLH C = 50 pF V = 5 V ns L CC t An to Bn or Bn to An 2.9 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 74ABT245D SOT163-1 20-Pin Plastic SSOP Type II 40 C to +85 C 74ABT245DB SOT339-1 20-Pin Plastic TSSOP Type I 40 C to +85 C 74ABT245PW SOT360-1 PIN CONFIGURATION PIN DESCRIPTION PIN SYMBOL NAME AND FUNCTION DIR 1 20 V NUMBER CC A0 2 19 OE 1 DIR Direction control input A1 3 18 B0 2, 3, 4, 5, A0 A7 Data inputs/outputs (A side) 6, 7, 8, 9 A2 4 17 B1 18, 17, 16, A3 5 16 B2 15, 14, 13, B0 B7 Data inputs/outputs (B side) A4 6 15 B3 12, 11 A5 7 14 B4 19 OE Output enable input (active-LOW) 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 2003 Feb 06
