TC74LCX14F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX14F, TC74LCX14FK Low-Voltage Hex Schmitt Inverter with 5-V Tolerant Inputs and Outputs The TC74LCX14 is a high-performance CMOS Schmitt inverter. TC74LCX14F 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 inputs. Pin configuration and function are the same as the TC74LCX04 but the inputs have hysteresis and with Schmitt trigger function, the TC74LCX14 can be used as line receivers which will receive slow input signals. All inputs are equipped with protection circuits against static TC74LCX14FK discharge. Features Low-voltage operation: V = 1.65 to 3.6 V CC High-speed operation: tpd = 6.5 ns (max) (VCC = 3.0 to 3.6 V) Ouput current: I /I = 24 mA (min) (V = 3.0 V) OH OL CC Available in JEITA SOP, VSSOP (US) Power-down protection provided on all inputs and outputs Weight Pin and function compatible with the 74 series SOP14-P-300-1.27A : 0.18 g ( typ.) (74AC/VHC/HC/F/ALS/LS etc.) 14 type VSSOP14-P-0030-0.50 : 0.02 g ( typ.) Note: The Electrical Characteristics of V = 1.8 0.15 V is only applicable for products which manufactured CC from January 2009 onward.
