| TC7MZ373FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MZ373FK Low-Voltage Octal D-Type Latch with 5 V Tolerant Inputs and Outputs The TC7MZ373FK is a high performance CMOS octal D-type latch. 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 a 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. Weight: 0.03 g (typ.) Features * * * * * * * Low voltage operation: VCC = 2.0~3.6 V High speed operation: tpd = 8.0 ns (max) (VCC = 3.0~3.6 V) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) Latch-up performance: 500 mA Package: VSSOP (US20) Power down protection is provided on all inputs and outputs. Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 373 type. 000630EBA1 * TOSHIBA is continually working to improve the quality and reliability of its products.
