74FCT3244/A 3.3V CMOS OCTAL BUFFER/LINE DRIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS OCTAL 74FCT3244/A BUFFER/LINE DRIVER DESCRIPTION: FEATURES: 0.5 MICRON CMOS Technology The FCT3244/A octal buffer/line drivers are built using advanced dual ESD > 2000V per MIL-STD-883, Method 3015 > 200V using metal CMOS technology. These high-speed, low-power buffers are machine model (C = 200pF, R = 0) designed to be used as memory data and address drivers, clock drivers, VCC = 3.3V 0.3V, Normal Range and bus-oriented transmitter/receivers. The three-state controls are VCC = 2.7V to 3.6V, Extended Range designed to operate these devices in a dual-nibble or single-byte mode. All CMOS power levels (0.4W typ. static) inputs are designed with hysteresis for improved noise margin. Rail-to-Rail output swing for increased noise margin Available in QSOP, SOIC, SSOP, and TSSOP packages FUNCTIONAL BLOCK DIAGRAM 1 1OE 2 18 1A1 1Y1 4 16 1A2 1Y2 14 6 1A3 1Y3 8 12 1A4 1Y4 19 2OE 11 9 2A1 2Y1 13 7 2A2 2Y2 5 15 2A3 2Y3 17 3 2A4 2Y4 INDUSTRIAL TEMPERATURE RANGE 1 Feb.11.2074FCT3244/A 3.3V CMOS OCTAL BUFFER/LINE DRIVER INDUSTRIAL TEMPERATURE RANGE (1) ABSOLUTE MAXIMUM RATINGS PIN CONFIGURATION Symbol Description Max Unit (2) VTERM Terminal Voltage with Respect to GND 0.5 to +4.6 V (3) VTERM Terminal Voltage with Respect to GND 0.5 to +7 V Vcc 1OE 1 (4) 20 VTERM Terminal Voltage with Respect to GND 0.5 to VCC+0.5 V 1A 1 2 19 2OE TSTG Storage Temperature 65 to +150 C Y 2 4 IOUT DC Output Current 60 to +60 mA 3 18 1Y1 NOTES: 1A2 2A4 4 17 1.
