TC74LCX373F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX373F, TC74LCX373FK Low-Voltage Octal D-Type Latch with 5-V Tolerant Inputs and Outputs The TC74LCX373 is a high-performance CMOS octal D-type latch. TC74LCX373F 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 both inputs and outputs. This 8 bit D-type latch is controlled by a latch enable input (LE) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high-impedance state. All inputs are equipped with protection circuits against static discharge. TC74LCX373FK Features Low-voltage operation: V = 1.65 V to 3.6 V CC High-speed operation: tpd = 8.0 ns (max) (VCC = 3.0 to 3.6 V) Output 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 Pin and function compatible with the 74 series Weight SOP20-P-300-1.27A : 0.22 g ( typ.) (74AC/VHC/HC/F/ALS/LS etc.) 373 type VSSOP20-P-0030-0.50 : 0.03 g ( typ.) Note: The Electrical Characteristics of VCC = 1.8 0.15 V is only applicable for products which manufactured from January 2009 onward.
