Buffers

8-channel buffer3-state outputCMOS logicCDIP

SN54HC244J is an 8-channel CMOS buffer and line driver with active-low 3-state outputs, a 2 V to 6 V supply range, and a 20-pin CDIP package.

Best for

  • 3-state bus buffering
  • Address and clock signal driving
  • High-temperature or military-grade logic assemblies

Avoid if

  • A surface-mount package is required
  • The application needs outputs that tolerate voltages above VCC

Check before use

  • Pin mapping and CDIP land pattern
  • Output-enable sequencing and bus contention
  • Per-output and total supply or ground current

Questions & answers

It is an eight-channel non-inverting CMOS buffer and line driver arranged as two independently enabled 4-bit sections. The outputs enter a high-impedance state when the corresponding active-low output-enable input is high.
