IN74LV244 Datasheet | IK Semiconductor

TECHNICAL DATA OCTAL BUFFER/LINE DRIVE; 3-STATE The IN74LV244 is a low-voltage Si-gate CMOS device and is pin and function patible with IN74HC/HCT244. The IN74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on n OE causes the outputs to assume a high impedance OFF-state. The IN74LV244 is identical to the IN74LV240 but has non-inverting outputs. - - - - - Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 1.2 to 3.6 V Low Input Current: 1.0 µA, 0.1 µА at Т = 25 °С Output Current: 8 m A at VCC = 3.0 V High Noise Immunity Characteristic of CMOS Devices N SUFFIX PLASTIC DIP 1 20 1 DW SUFFIX SO ORDERING INFORMATION IN74LV244N Plastic DIP IN74LV244DW SOIC TA = -40° to 125° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT 1A0 1A1 1A2 1A3 DATA INPUTS 2A0 2A1 2 4 6 8 11 13 18 16 14 12 9 7 5 3 1Y0 1Y1 1Y2 1Y3 2Y0 2Y1 2Y0 2Y1 NONINVERTING OUTPUTS 1OE 1A0 2Y3 1A1 2Y2 1A2 2Y1 1A3 2Y0 GND 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC 2OE 1Y0 2A3 1Y1 2A2 1Y2 1Y3 2A0 2A0 15 2A1 17 OUTPUT ENABLES 1OE 2OE 1 19 FUNCTION TABLE Input Output n An L H X n Yn L H Z n OE L L H w w a d . w e h s a t 4 t e u. m o c PIN 20=VCC PIN 10 = GND H= high level L = low level X = don’t care Z = high impedance .. 2A1 MAXIMUM RATINGS- Symbol VCC IIK - IO - ICC IGND PD Parameter DC supply voltage DC Input diode current DC Output diode current DC Output source or sink current DC VCC current DC GND current Power dissipation per package: - Plastic DIP SO Storage Temperature Lead Temperature, 1.5 mm (Plastic DIP Package), 0.3 mm (SO Package) from Case for 4 Seconds Value -0.5 to +5.0 ±20 ±50 ±35 ±70 ±70 750 500 -65 to +150 260 Unit V m A m A m A m A m A m...
