TC74VCX16834FT Datasheet Low-voltage 18-bit Universal Bus Driver

Manufacturer: Toshiba

Overview: TC74VCX16834FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX16834FT Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs The TC74VCX16834FT is a high-performance CMOS 18-bit universal bus driver. 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. Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CK) input is held at a high or low logic level. If LE is high, the A data is Weight: 0.25 g (typ.) stored in the latch/flip-flop on the low-to-high transition of CK. When OE is high, the outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge.

Key Features

  • Low-voltage operation: VCC = 1.8 to 3.6 V.
  • High-speed operation: tpd = 3.3 ns (max) (VCC = 3.0 to 3.6 V) : tpd = 4.2 ns (max) (VCC = 2.3 to 2.7 V) : tpd = 8.4 ns (max) (VCC = 1.8 V).
  • Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V) : IOH/IOL = ±18 mA (min) (VCC = 2.3 V) : IOH/IOL = ±6 mA (min) (VCC = 1.8 V).
  • Latch-up performance:.
  • 300 mA.
  • ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V.
  • Package: TSSOP.
