8 / 20 page SN74AHCT1G86 SCLS324M – MARCH 1996 – REVISED MARCH 2015 www.ti.com 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. 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. 9.1 Application Information The SN74AHCT1G86 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 2-V VIH. This feature makes it Ideal for translating up from 3.3 V to 5 V. 9.2 Typical Application Figure 4. Typical Application Schematic 9.2.1 Design Requirements This device uses CMOS technology and has balanced output drive. Take care 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 consider routing and load conditions to prevent ringing. 9.2.2 Detailed Design Procedure • Recommended input conditions: – Rise time and fall time specs. See ( Δt/ΔV) in Recommended Operating Conditions. – Specified high and low levels. See (VIH and VIL) in Recommended Operating Conditions. • Recommended 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. 8 Submit Documentation Feedback Copyright © 1996–2015, Texas Instruments Incorporated Product Folder Links: SN74AHCT1G86 |
