TC74VCX162827FT

The TC74VCX162827FT is a high-performance CMOS 20-bit bus buffer. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V.The TC74VCX162827FT is composed of two 10-bit sections with separate output-enable signals. For either 10-bit buffer section, the two output-enable (1OE1 and 1OE2 or 2 OE1 and 2 OE2) inputs must both be low for the corresponding Y outputs to be active. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc.

Features of the TC74VCX162827FT are:(1)low voltage operation:VCC=1.8 to 3.6 V;(2)high speed operation:tpd=3.4 (max) at VCC=3.0 to 3.6 V, tpd=4.1 (max) at VCC=2.3 to 2.7 V,tpd=8.2(max) at VCC=1.8 V;(3)output current:Ioh/IOL=±12 mA (min) at VCC=3.0V,IOH/COL=±8mA (min) at VCC=2.3 V,IOH/COL=±4 mA (min) at VCC=1.8 V;(4)latch-up performance:-300 mA;(5)ESD performance:human body model>±2000 V,machine model>±200 V;(6)package:TSSOP;(7)26- series resistors on outputs;(8)3.6-V tolerant function and power-down protection provided on all inputs and outputs.

The absolute maximum ratings of the TC74VCX162827FT can be summarized as:(1)power supply voltages:-0.5 to +4.6 V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 4.6 V;(4)input diode current:-50mA;(5)power dissipation:400mW.Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,etc.).These TOSHIBA products are neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or bodily injury ("Unintended Usage").
