TC74LVX273F

The TC74LVX273F is one member of the TC74LVX273 series.The TC74LVX273 is a high speed CMOS octal D-flip flop fabricated with silicon gate C2MOS technology.Designed for use in 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation.This device is suitable for low voltage and battery operated systems.Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse.

Features of the TC74LVX273F are:(1)High speed:fMAX=150MHz (Typ.) (VCC=3 V); (2)Low power dissipation:ICC=4A (Max.) (Ta=25); (3)Input voltage level:VIL=0.8V (Max.) (VCC=3 V),VIH=2.0V (Min.) (VCC=3V); (4)Balanced propagation delays:tpLHtpHL; (5)Low noise:VO LP=0.8V (Max.); (6)Pin and function compatible with 74HC273.When the CLR input is held low, the Q outputs are in the low logic level independent of the other inputs.An input protection circuit ensures that 0 to 7V 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 TC74LVX273F 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.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").
