TC74LVX240F

The TC74LVX240F is one member of the TC74LVX240 series.The TC74LVX240 is a high-speed CMOS octal bus buffer fabricated using 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.The information contained herein is presented only as a guide for the applications of our products. No responsibility is assumed by TOSHIBA for any infringements of patents or other rights of the third parties which may result from its use. No license is granted by implication or otherwise under any patents or other rights of TOSHIBA or the third parties.

Features of the TC74LVX240F are:(1)High speed:tpd=4.7ns(typ.)(VCC=3.3 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 74HC240.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 TC74LVX240F 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;(7)output diode current:±20 mA;(8)DC output current:±25 mA;(9)DC Vcc/ground current:±75 mA.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").
