TC74VCXHR162245FT
Low-Voltage 16-Bit Bus Transceiver with Bushold
The TC74VCXHR162245FT is a high-performance CMOS 16-bit bus 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. This 16-bit bus transceiver is controlled by direction control (DIR) inputs and output enable (OE) inputs which are common to each byte. It can be used as two 8-bit transceivers or one 16-bit transceiver. The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable the device so that the busses are effectively isolated. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. Weight: 0.25 g (typ.) The A, B data inputs include active bushold circuitry, eliminating the need for external pull-up resisisors to hold unused or floating data inputs at a valid logic level. All inputs are equipped with protection circuits against static discharge.
Features
* * * * 26- series resistors on all 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 = 3.4 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.3 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 5.7 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 (thin shrink small outline package)
Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
