| TC74VCXHR162543FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCXHR162543FT Low-Voltage 16-Bit Registered Transceiver with Bushold The TC74VCXHR162543FT is a high-performance CMOS 16-bit registered transceiver. 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. The TC74VCXHR162543FT can be used as two 8-bit transceivers or one 16-bit transceiver. Separate latch-enable (LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are provided for each register to permit independent control in either direction of data flow. The A-to-B enable (CEAB) input must be low in order to enter Weight: 0.25 g (typ.) data from A or to output data from B. If CEAB is low and LEAB is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB puts the Alatches in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar but requires using the CEBA, LEBA, and OEBA inputs. 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. The A, B data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level. All inputs are equipped with protection circuits against static discharge. Features (Note) * * * * 26- series resistors on outputs Low-voltage operation: VCC = 1.8 to 3.6 V Bushold on data inputs eliminating the need for external pull-up/pull-down resistors High-speed operation: tpd = 4.4 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 5.4 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 9.8 ns (max) (VCC = 1.8 V) * * 3.6-V tolerant control inputs Output current: IOH/IOL = 12 mA (min) (VCC = 3.0 V) : IOH/IOL = 8 mA (min) (VCC = 2.3 V) : IOH/IOL = 4 mA (min) (VCC = 1.8 V) * * * Latch-up performance: -300 mA ESD performance: Machine model 200 V Human body model 2000 V Package: TSSOP Note: Do not apply a signal to any bus pins when it is in the output mode.
