SN54LS74Adual D flip-flopLS-TTLpositive-edge triggeredactive-low presetactive-low clearCDIP-14military temperature

SN54LS74AJ is a 14-pin ceramic, military-temperature dual LS-TTL D flip-flop with rising-edge clocking and asynchronous active-low preset and clear.

Best for

  • 5 V TTL sequential logic
  • Military-temperature digital control circuits
  • Through-hole ceramic designs

Avoid if

  • A low-voltage CMOS interface is required
  • A surface-mount-only assembly is required
  • A lead-free-only component requirement applies

Check before use

  • Confirm CDIP-14 package fit and pinout
  • Validate clock pulse width and setup/hold timing
  • Verify present distributor inventory and compliance requirements
