TC74VCXH162374FT
Low-Voltage 16-Bit D-Type Flip-Flop with Bushold
The TC74VCXH162374FT is a high-performance CMOS 16-bit D-type flip-flop. 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 D-type flip-flop is controlled by a clock input (CK) and a output enable input (OE) which are common to each byte. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. When the OE input is high, the outputs are in a high impedance state. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. The D data inputs include active bushold circuitry, eliminating the need for external pull-up resisisors to hold unused or floating Weight: 0.25 g (typ.) data inputs at a valid logic level. All inputs are equipped with protection circuits against static discharge.
Features
* * * * 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 = 3.4 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.8 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 6.0 ns (max) (VCC = 1.8 V) * 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) 3.6-V tolerant function and power-down protection control inputs and outputs
