TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information The SN74AHCT1G125 is a low-drive CMOS device that can be used for a multitude of bus interface type applications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on the outputs. The input switching levels have been lowered to accommodate TTL inputs of 0.8 V VIL and 2V VIH. This feature makes it Ideal for translating up from 3.3 V to 5 V. Figure 4 shows this type of translation. 10.2 Typical Application Figure 4. Typical Application Schematic 10.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edges into light loads, so routing and load conditions should be considered to prevent ringing. 10.2.2 Detailed Design Procedure 1. Recommended Input Conditions – For rise time and fall time specifications, see Δt/ΔV in the Recommended Operating Conditions table. – For specified High and low levels, see VIH and VIL in the Recommended Operating Conditions table. – Inputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC. 2. Recommend Output Conditions – Load currents should not exceed 25 mA per output and 50 mA total for the part. – Outputs should not be pulled above VCC. |
