Descripción

Productos

The SN74AHC1G125DBVR from Texas Instruments is a single bus buffer gate with 3-state output in a compact SOT-23-5 (DBV) package. Operating from 2V to 5.5V, it provides low-power bus buffering with 10µA max ICC and ±8mA output drive at 5V, making it ideal for signal buffering and bus isolation in space-constrained designs.

Características

  • Operating range of 2V to 5.5V
  • Maximum tpd of 6 ns at 5V
  • Low power consumption, 10µA max ICC
  • ±8mA output drive at 5V
  • 3-state output with active-high output enable (OE)
  • Balanced propagation delays
  • Overvoltage tolerant inputs
  • Latch-up performance exceeds 250mA per JESD 17

Aplicaciones

  • Bus buffering and signal isolation
  • Level translation between 3.3V and 5V systems
  • Memory I/O port buffering
  • Board-level signal routing
  • Motor control and patient monitoring systems

The SN74AHC1G125DBVR is a single-channel bus buffer gate/line driver with 3-state output from the AHC logic family. When the output-enable (OE) input is high, the output is disabled (high-impedance). When OE is low, true data passes from the A input to the Y output. The device operates from 2V to 5.5V with a maximum propagation delay of 6 ns at 5V, making it suitable for high-speed signal buffering and bus isolation in mixed-voltage systems.

The SN74AHC1G125 consists of two main functional blocks: (1) 3-State Output Control: The OE (output enable) pin controls the output buffer state. When OE is HIGH, the output stage is placed in a high-impedance state, effectively disconnecting the device from the bus. When OE is LOW, the output is actively driven. (2) Non-Inverting Buffer: The input signal at pin A passes through a CMOS buffer stage to the Y output without inversion. The AHC (Advanced High-Speed CMOS) technology provides fast switching (6ns tpd at 5V) while maintaining low static power consumption (10µA max ICC).
