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-Ω series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge.
