INTEGRATED CIRCUITS 74ALVT162244 2.5V/3.3V 16-bit buffer/driver with 30 termination resistors (3-State) Product specification 1998 Oct 07 Supersedes data of 1998 Feb 13 IC23 Data Handbook Philips Semiconductors Product specification 2.5V/3.3V 16-bit buffer/driver with 74ALVT162244 30 termination resistors (3-State) FEATURES DESCRIPTION The 74ALVT162244 is a high-performance BiCMOS product 16-bit bus interface designed for V operation at 2.5V or 3.3V with I/O compatibility up CC 3-State buffers to 5V. 5V I/O compatibile The 74ALVT162244 is designed with 30 series resistance in both the High and Low states of the output. This design reduces line Output capability: +12mA/-12mA noise in applications such as memory address drivers, clock drivers, TTL input and output switching levels and bus receivers/transmitters. Input and output interface capability to systems at 5V supply This device is a 16-bit buffer and line driver featuring non-inverting Bus-hold data inputs eliminate the need for external pull-up 3-State bus outputs. The device can be used as four 4-bit buffers, resistors to hold unused inputs two 8-bit buffers, or one 16-bit buffer. Live insertion/extraction permitted Outputs include series resistance of 30 making external terminating resistors unnecessary 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 TYPICAL CONDITIONS SYMBOLSYMBOL PPARAMETERARAMETER UNITUNIT T = 25C amb 2.5V 3.3V t Propagation delay 2.7 2.2 PLH C = 50pF ns L t nAx to nYx 2.3 2.2 PHL C Input capacitance DIR, OE V = 0V or V 3 3 pF IN I CC C Output capacitance V = 0V or V 9 9 pF Out I/O CC I Total supply current Outputs disabled 40 70 A CCZ ORDERING INFORMATION PACKAGES TEMPERATURE RANGE OUTSIDE NORTH AMERICA NORTH AMERICA DWG NUMBER 48-Pin Plastic SSOP Type III 40C to +85C 74ALVT162244 DL AV162244 DL SOT370-1 48-Pin Plastic TSSOP Type II 40C to +85C 74ALVT162244 DGG AV162244 DGG SOT362-1 LOGIC SYMBOL PIN DESCRIPTION PIN NUMBER SYMBOL NAME AND FUNCTION 1A0 3A0 1Y0 3Y0 47 2 36 13 47, 46, 44, 43 1A0 - 1A3, 41, 40, 38, 37 2A0 - 2A3, Data inputs 1A1 1Y1 3A1 3Y1 36, 35, 33, 32 3A0 - 3A3, 46 3 35 14 30, 29, 27, 26 4A0 - 4A3 1A2 1Y2 3A2 3Y2 44 5 33 16 2, 3, 5, 6 1Y0 - 1Y3, 8, 9, 11, 12 2Y0 - 2Y3, 1A3 1Y3 3A3 3Y3 Data outputs 43 6 32 17 13, 14, 16, 17 3Y0 - 3Y3, 19, 20, 22, 23 4Y0 - 4Y3 1OE 3OE 1 25 1, 48 1OE, 2OE, 3OE, 2A0 4A0 4Y0 Output enables 2Y0 41 8 30 19 25, 24 4OE 2A1 4A1 2Y1 4Y1 4, 10, 15, 21 40 9 29 20 GND Ground (0V) 28, 34, 39, 45 2A2 4A2 4Y2 2Y2 38 11 27 22 7, 18, 31, 42 V Positive supply voltage CC 2Y3 4Y3 2A3 4A3 37 12 26 23 4OE 2OE 48 24 SA00014 2 1998 Oct 07 853-1841 20144
