74HC6323A; 74HCT6323A Programmable ripple counter with oscillator; 3-state Rev. 4 — 9 July 2018 1 Product data sheet General description The 74HC6323A; 74HCT6323A is an oscillator designed for quartz crystal combined with a programmable 3-state counter, a 3-state output buffer and an overriding asynchronous master reset (MR). With the two select inputs S1 and S2 the counter can be switched in the divide-by-1, 2, 4 or 8 mode. If left floating the clock is divided by 8. The oscillator is designed to operate either in the fundamental or third overtone mode depending on the crystal and external components applied. On-chip capacitors minimize external component count for third overtone crystal applications. The oscillator may be replaced by an external clock signal at input X1. In this event the other oscillator pin (X2) must be floating. The counter advances on the negative-going transition of X1. A LOW level on MR resets the counter, stops the oscillator and sets the output buffer in the 3-state condition. MR can be left floating since an internal pull-up resistor will make the MR inactive. The X1 input has CMOS input switching levels and may be driven by a TTL output using a pull-up resistor connected to VCC. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2 Features and benefits • • • • • • • Programmable 3-stage ripple counter Suitable for over-tone crystal application up to 50 MHz (VCC = 5 V ± 10%) 3-state output buffer Two internal capacitors Recommended operating range for use with third overtone crystals 3 to 6 V Oscillator stop function (MR) Input levels: – For 74HC6323: CMOS level – For 74HCT6323: TTL level • ESD protection: – HBM JESD22-A114-A exceeds 2000 V – MM JESD22-A115-A exceeds 200 V • Specified from -40 °C to +85 °C and from -40 °C to +125 °C 74HC6323A; 74HCT6323A Nexperia Programmable ripple counter with oscillator; 3-state 3 Applications • • • • • • 4 Control counters Timers Frequency dividers Time-delay circuits CIO (Compact Integrated Oscillator) Third-overtone crystal operation Ordering information Table 1. Ordering information Type number 74HC6323AD Package Temperature range Name Description Version -40 °C to +125 °C SO8 plastic small outline package; 8 leads; body width 3.9 mm SOT96-1 74HCT6323AD 5 Functional diagram 6 7 5 X2 X1 CP MR CD 3 S1 2 S2 OUT 1 aaa-028595 Figure 1. IEC logic symbol 6 X2 7 X1 5 MR CP CD 3 - STAGE BINARY COUNTER AND DECODER S1 3 S2 2 OUT 1 aaa-028596 Figure 2. Functional diagram 74HC_HCT6323A Product data sheet All information provided in this document is subject to legal disclaimers.

For starting and maintaining oscillation a minimum transconductance is necessary, so R2 should not be too large. A practical value for R2 is 2.2 kΩ. The oscillator has been designed to operate over a wide frequency spectrum, for quartz crystals operating in the fundamental mode and in the overtone mode. The circuit is a Pierce type oscillator and requires a minimum of external components. There are two on-chip capacitors, X1 and X2, of approximately 7 pF. Together with the stray and input capacitance the value becomes 12 pF for 8-pin SO packages. These values are convenient and make it possible to run the oscillator in the third overtone without external capacitors applied. If a certain frequency is chosen, the IC parameters, as forward transconductance, and the crystal parameters such as the motional resistances R1 (fundamental), R3 (third overtone) and R5 (fifth overtone), are of paramount importance. Also the values of the external components as Rs (series resistance) and the crystal load capacitances play an important role. Especially in overtone mode oscillations, Rb (bias resistance) and the load capacitance values are very important. 74HC_HCT6323A Product data sheet All information provided in this document is subject to legal disclaimers.

The value must be high, i.e. 100 kΩ up to 10 MΩ. The load capacitors C1 and C2, must have a value that is suitable for the crystal being used. The crystal is designed for a certain frequency having a specific load capacitance. C1 can be used to trim the oscillation frequency. The series resistance reduces the total loop gain. One function of it is therefore to reduce the power dissipation in the crystal. Rs also suppresses overtone oscillations and introduces a phase shift over a broad frequency range. This is of less concern provided Rs is not too high a value. Note: A combination of a small load capacitor value and a small series resistance, may cause a third overtone oscillation. 12.3 Considerations for Third-overtone Oscillator: In the overtone configuration, series resistance is no longer applied. This is essential otherwise the gain for third overtone can be too small for oscillation. A simple solution to suppress the fundamental oscillation, is to spoil the crystal fundamental activity. By dramatically reducing the value of the bias resistor of the inverting stage, and applying small load capacitors, it is possible to have an insufficient phase in the total loop for fundamental oscillation. However the phase for third overtone is good. It can be explained by the Rb × Cl time constant. During oscillation the crystal with the load capacitors cause a phase shift of 180°. Because Rb is parallel with the crystal (no Rs), Rb spoils the phase for fundamental. Rb × Cl must be of a value, that it is not spoiling the phase for third overtone too much. Because third overtone is a 3 times higher frequency than the fundamental, the Rb × Cl cannot 'maintain' the higher third overtone frequency, which results in a less spoiled overtone phase. 74HC_HCT6323A Product data sheet All information provided in this document is subject to legal disclaimers.
