SN74ALVCH244的产品详情:

This octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operation.

The SN74ALVCH244 is organized as two 4-bit line drivers with separate output-enable (OE)\ inputs. When OE\ is low, the device passes data from the A inputs to the Y outputs. When OE\ is high, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

SN74ALVCH244的优势和特性:
  • Operates From 1.65 V to 3.6 V
  • Max tpd of 2.8 ns at 3.3 V
  • ±24-mA Output Drive at 3.3 V
  • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
  • Latch-Up Performance Exceeds 250 mA Per JESD 17
  • ESD Protection Exceeds JESD 22
    • 2000-V Human-Body Model (A114-A)
    • 200-V Machine Model (A115-A)
