Texas Instruments SN74HCS245/SN74HCS245-Q1 Octal Bus Transceivers
Texas Instruments SN74HCS245/SN74HCS245-Q1 Octal Bus Transceivers provide 3-state outputs and Schmitt-trigger inputs. The Schmitt-trigger inputs allow for slow or noisy input signals. The SN74HCS245/SN74HCS245-Q1 implements eight channels controlled by the direction (DIR) pin and output-enable (OE) pin. The devices feature a wide operating voltage range of 2V to 6V.
The TI SN74HCS245/SN74HCS245-Q1 Octal Bus Transceivers are available in a 20-VQFN or wettable flank QFN (WRKS) package with an extended ambient temperature range of –40°C to +125°C.
