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 9.1.1 TTL-to-HC Interface TTL output voltages and HC input voltages are incompatible, especially between the TTL high-level output voltage (VOH) and the HC high-level input voltage (VIH). This problem can be solved in two different ways. The first solution is to provide pullup resistors at the TTL outputs to ensure an adequate high-level TTL output voltage. A alternative method requires the use of level shifters. 9.2 Typical Application +5 V Rp Figure 11. Typical Application Schematic TTL-to-HC Interface Using Open-Collector Output. 9.2.1 Design Requirements Interfacing TTL open-collector outputs to HC-CMOS inputs requires design of pullup circuit balanced with drive capability to achieve timing and VOL-HC input specifications. Similar technique can be applied when using opendrain outputs. 9.2.2 Detailed Design Procedure Using pullup resistors to accommodate TTL output signals to interface with HC input circuits (see Figure 11), the design engineer must choose the resistance that is appropriate for the application. The minimum value of the resistor is determined by the maximum current IOL that a TTL circuit can supply at the low-level output (VOL). V max - VOLmin Rp min = CC IOL + n ´ IIL where • • n is the number of HC inputs to be driven IIL is their input current (1) IIL, having a value of only a few nanoamperes, is negligible in all calculations. In the case of a SN74ALS03, Equation 2 defines Rpmin: 5.5V - 0.4V = 640W Rp min = 8mA (2) To calculate the upper limit of this resistor, a sufficient VIH high level must be ensured. V - VIH min Rp max = CC n ´ IIH (3) In this situation, the input current of HC devices is negligible and very high values also are obtained. 12 Submit Documentation Feedback Copyright © 2002–2015, Texas Instruments Incorporated Product Folder Links: CD74HC4051-EP CD74HC4051-EP www.ti.com SCLS464A – SEPTEMBER 2002 – REVISED JANUARY 2015 Typical Application (continued) When calculating the maximum allowable resistance, it is important to ensure that the maximum allowable rise time (tr = 500 ns) at the HC input is not exceeded. Equation 4 then applies: VIH = VCC (1 - e -t Rp ´C ) where • C is the total load capacitance in the circuit (4) C is composed of the output capacitance of the driving gate (approximately 10 pF), the total input capacitances of gates to be driven (approximately 5 pF each), and the line capacitance (approximately 1 pF/cm). The actual value is calculated by solving the equation for Rp: -t Rp = 3.5V C ´ ln(1 ) 5V (5) Assuming the total capacitance, C, is 30 pF, the maximum resistor is: -500ns Rp = = 14kW 3.5V 30pF ´ ln(1 ) 5V (6) Faster rise times result in lower impedance and more power consumption. The previous calculation is based on the assumption that the driving gate has an open collector. Conditions become more satisfactory, however, when a gate with totem-pole output (that is, SN74ALS00) is used. In that case, the gate output provides the voltage to be brought up to the value VOH = 2.7 V in less than 10 ns (the rise time of the TTL signal). The pullup resistor only has to pull the level to 3.5 V within the desired time. According to the previous formula, and with a required rise time of tr = 50 ns, the resistor is defined by Equation 7: -50ns - 10ns Rp max = = 3.12kW 3.5V - 2.7 V 30pF ´ ln(1 ) 5V - 2.7V (7) The upper limiting value of the resistor is primarily dictated by the rise time required. The larger the resistance, the longer the rise times and propagation delay times. Reducing the resistance increases speed and power dissipation. The other method of accommodating TTL signals to HC circuits is accomplished with special level shifters. This solution is not recommended because the level shifter itself has no inherent logic functions and increases component and space requirements.

These transistors are designed to sink the same input current at the required threshold voltage. The resulting voltage at the output is equivalent to 50% of the supply voltage VCC. For an HC circuit, the channel width of the P-channel transistor of the input is approximately twice the value of an N-channel transistor. The purpose is to make both transistors have the same current characteristics, thus making the threshold voltage of their input at about 50% of the supply voltage VCC. 11 Layout 11.1 Layout Guidelines Analog channels inputs and outputs should be routed to optimize system requirements. VCC and VEE should have local decoupling capacitance placed close to device.
