SN74ACT244-EP Datasheet | Texas Instruments

FEATURES - Controlled Baseline - One Assembly/Test Site, One Fabrication Site - Extended Temperature Performance of up to - 55°C to 125°C - Enhanced Diminishing Manufacturing Sources (DMS) Support - Enhanced Product-Change Notification - Qualification Pedigree (1) - 4.5-V to 5.5-V VCC Operation - Inputs Accept Voltages to 5.5 V - Max tpd of 9.5 ns at 5 V - Inputs Are TTL patible (1) ponent qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold pound life. Such qualification testing should not be viewed as justifying use of this ponent beyond specified performance and environmental limits.

The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes noninverted 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. - 55°C to 125°C - 40°C to 85°C SOIC - DW SOP - NS SOIC - DW ORDERING INFORMATION PACKAGE (1) ORDERABLE PART NUMBER Tape and reel SN74ACT244MDWREP Tape and reel SN74ACT244MNSREP...
