NLA16T245 16-Bit (Dual 8-Bit) Configurable Dual-Supply Translating Transceiver with 3-State Outputs The NLA16T245 is a 16−bit (dual 8−bit) configurable dual−supply translating bidirectional transceiver with 3−state outputs. The A− and B−ports are designed to track two different power supply rails, VCCA and VCCB respectively. Both supply rails are configurable from 0.9 V to 4.5 V allowing universal bidirectional voltage translation between the A− and B−ports. The Direction inputs, 1DIR and 2DIR,.

NLA16T245 16-Bit (Dual 8-Bit) Configurable Dual-Supply Translating Transceiver with 3-State Outputs The NLA16T245 is a 16−bit (dual 8−bit) configurable dual−supply translating bidirectional transceiver with 3−state outputs. The A− and B−ports are designed to track two different power supply rails, VCCA and VCCB respectively. Both supply rails are configurable from 0.9 V to 4.5 V allowing universal bidirectional voltage translation between the A− and B−ports. The Direction inputs, 1DIR and 2DIR, determine the direction of data flow. 1DIR and 2DIR are independent of each other. When 1DIR or 2DIR is High, data flows from 1An to 1Bn or 2An to 2Bn respectively. When 1DIR or 2DIR is Low, data flows from 1Bn to 1An or 2Bn to 2An respectively. The Output Enable inputs, and , when High, disables both A− and B−ports by putting them in 3−state. The 1DIR, 2DIR, and signals are all designed to track VCCA. Features • Wide VCCA and VCCB Operating Range: 0.9 V to 4.5 V • Output Noise Reduction through Dynamic Output Impedance Change • Drive Capability: ±12 mA @ 3.0 V VCC • Input/Output Pins OVT to 5.5 V • Control Inputs Track VCCA • Non−preferential VCC Sequencing • Outputs at 3−State until Active VCC is reached • Power−Off Protection • Outputs Switch to 3−State with either VCC at GND • Pb−Free Packaging: TSSOP−48 • This is a Pb−Free Device Typical Applications • Mobile Phones, PDAs, Other Portable Devices Important Information • ESD Protection for All Pins: Human Body Model (HBM) > 2000 V Machine Model (MM) > 200 V http://onsemi.com TSSOP−48 DT SUFFIX 1 CASE1201 MARKING DIAGRAM NLA16T245G AWLYYWW 1 XXXXX = Specific Device Code A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package ORDERING INFORMATION Device Package Shipping† NLA16T245DTR2G TSSOP−48 2500 / Tape & (Pb−Free) Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D. © Semiconductor Components Industries, LLC, 2013 September, 2013 − Rev. 0 1 Publication Order Number: NLA16T245/D NLA16T245 Figure 1.
