TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic Low-Voltage 16-Bit Registered Transceiver with Bushold The TC74VCXH16543FT 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 TC74VCXH16543FT 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 data from A or to output data from B. If CEAB is low and LEAB Weight: 0.25 g (typ.) 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 OEAB 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 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) - 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 = 3.5 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.0 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 8.0 ns (max) (VCC = 1.8 V) - 3.6-V tolerant control inputs - Output current: IOH/IOL = ±24 m A (min) (VCC = 3.0 V) : IOH/IOL = ±18 m A (min) (VCC = 2.3 V) : IOH/IOL = ±6 m A (min) (VCC = 1.8 V) - Latch-up performance: - 300 m A - ESD...
