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 SN74HC132 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 minimize overshoot and undershoot on the outputs. The inputs can accept voltages to VCC. The current consumption of the device is low with maximum 20-µA ICC. 9.2 Typical Application Figure 5. Typical Application Diagram 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 also creates fast edges into light loads, so consider routing and load conditions to prevent ringing. 9.2.2 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. 2. Recommend Output Conditions: – Load currents should not exceed 25 mA per output and 50 mA total for the part. – Outputs must not be pulled above VCC. |
