AHCToctal bus transceiverbidirectional3-stateTTL-compatible input5 V logicVQFN-20

SN74AHCT245RKSR is a 5 V octal bidirectional bus transceiver with TTL-compatible inputs and 3-state bus isolation, supplied in a compact 20-pin RKS VQFN package.

Best for

  • 5 V digital bus interfaces
  • TTL-compatible control signals
  • Bidirectional parallel bus isolation

Avoid if

  • The interface requires operation below 4.5 V
  • Independent direction control is required for individual channels
  • The bus can be driven from both sides at the same time

Check before use

  • Confirm DIR polarity: low transfers B to A and high transfers A to B.
  • Confirm OE is controlled or pulled high as required for power-up isolation.
  • Keep each output within the recommended ±8 mA load rating.
