| TC74VCX162843FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX162843FT Low-Voltage 18-Bit D-Type Latch with 3.6-V Tolerant Inputs and Outputs The TC74VCX162843FT is a high-performance CMOS 18-bit D-typr latch. Designed for use in 1.8-V, 2.5-V or 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V. The TC74VCX162843FT can be used as two 9-bit latches or one 18-bit latch. The 18 latches are transparent D-type latches. The device has noninverting data (D) inputs and provides true data at its outputs. While the latch-enable (1LE or 2LE) input is Weight: 0.25 g (typ.) high, the Q outputs of the corresponding 9-bit latch follow the D inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs. CLR and PR are independent of the CK and are accomplished by setting the appropriate input low. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
