TC7MZ244FK

TC7MZ244FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MZ244FK Low Voltage Octal Bus Buffer with 5 V Tolerant Inputs and Outputs The TC7MZ244FK is a high performance CMOS octal bus buffer. Designed for use in 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply environment for both inputs and outputs. The TC7MZ244FK is a non-inverting 3-state buffer having two active-low output enables. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge. Features Weight: 0.03 g (typ.) Low voltage operation: VCC = 2.0~3.6 V High speed operation: tpd = 6.5 ns (max) (VCC = 3.0~3.6 V) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) Latch-up performance: −500 mA Package: VSSOP (US20) Power down protection is provided on all inputs and outputs. Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 244 type. 1 2007-10-19 Pin Assignment (top view) 1OE 1 1A1 2 2Y4 3 1A2 4 2Y3 5 1A3 6 2Y2 7 1A4 8 2Y1 9 GND 10 20 VCC 19 2OE 18 1Y1 17 2A4 16 1Y2 15 2A3 14 1Y3 13 2A2 12 1Y4 11 2A1 IEC Logic Symbol 1 1OE EN 2 1A1 4 1A2 6 1A3 8 1A4 TC7MZ244FK 18 1Y1 16 1Y2 14 1Y3 12 1Y4 19 2OE EN 11 2A1 13 2A2 15 2A3 17 2A4 9 2Y1 7 2Y2 5 2Y3 3 2Y4 Truth Table Inputs OE An L L L H H X ...
