TC74LVX125FT

The TC74LVX125FT is one member of the TC74LVX125F series.The TC74LVX125F is a high-speed CMOS quad bus buffer fabricated with silicon gate CMOS technology. Designed for use in 3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This device is suitable for low-voltage and battery operated systems.This device requires the 3-state control input G to be set high to place the output into the high-impedance.

Features of the TC74LVX125FT are:(1)high speed:tpd=4.4ns (Typ.) (Vcc=3.3V);(2)low power dissipation:Icc=4A (Max)(Ta=25);(3)pin and function compatible with 74HC125;(4)power down protection is provided on all inputs;(5)balanced propagation delays:tpLHtpHL;(6)low noise:VOLP=0.5V (Max.);(7)Input voltage level: VIL=0.8 V (max) (VCC=3V),VIH=2.0 V (min) (VCC=3V).An input protection circuit ensures that 0 to 5.5V can be applied to the input pins without regard to the supply voltage.This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

The absolute maximum ratings of the TC74LVX125FT can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)storage temperature:-65 to +150;(3)DC input voltage:-0.5 to 7.0V;(4)input diode current:-20 mA;(5)DC output voltage:-0.5 to Vcc+0.5V;(6)power dissipation:180mW.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").
