Texas Instruments CD4093BM96

Overview

CD4093BM96 from Texas Instruments is a quad 2-input NAND Schmitt-trigger IC in SOIC-14 package, operating over -55°C to +125°C, with V_DD range 3 V–18 V, typical propagation delay 80 ns at 5 V, and input hysteresis of ±0.8 V (V_DD = 5 V). It serves as noise-immune logic gate for debouncing switches, oscillator circuits, and waveform shaping in industrial control interfaces.

For engineers reviewing the CD4093BM96 datasheet, CD4093BM96 pinout, CD4093BM96 application, or CD4093BM96 equivalent, key selection criteria include supply voltage tolerance, Schmitt-trigger hysteresis width, propagation delay vs. V_DD, thermal impedance (86°C/W), and SOIC-14 tape-and-reel packaging for automated assembly.

Technical Context

The CD4093BM96 implements four independent 2-input NAND gates, each with built-in Schmitt-trigger action on both inputs-enabling clean digital transitions from slow or noisy analog signals. Its CMOS architecture ensures low static current (≤1 µA at V_DD = 5 V) and rail-to-rail output swing.

Each gate features symmetric input hysteresis (ΔV_IN ≈ 1.6 V at V_DD = 5 V), enabling reliable signal conditioning without external components. The device supports direct interfacing with TTL, CMOS, and high-impedance sources across its full 3–18 V operating range.

FAQ

What is the maximum operating frequency of the CD4093BM96 in oscillator mode?

The CD4093BM96 supports stable astable operation up to approximately 100 kHz when configured with standard RC timing components and V_DD = 10 V. This limit arises from cumulative propagation delay (80 ns typical per gate) and input capacitance effects. For precise frequency setting, use the formula f ≈ 1/(1.4 × R × C), validated with actual CD4093BM96 measurements under load.

Can the CD4093BM96 drive an LED directly without a current-limiting resistor?

No - the CD4093BM96 requires an external current-limiting resistor for LED drive. While its output can source up to 4.2 mA at V_DD = 10 V, forward voltage and current requirements of typical LEDs exceed safe operating limits without series resistance. Always use a resistor calculated as R = (V_DD – V_F)/I_F to protect both the LED and the CD4093BM96 output stage.

Is the CD4093BM96 compatible with 3.3 V logic systems?

Yes - the CD4093BM96 operates down to 3 V, making it fully compatible with 3.3 V logic systems. At V_DD = 3.3 V, output high voltage reaches ≥2.9 V and output low remains ≤0.3 V, satisfying standard CMOS input thresholds. However, propagation delay increases to ~150 ns and hysteresis narrows to ±0.5 V, which should be verified in the target CD4093BM96 application.

Does the CD4093BM96 require external pull-up resistors on its inputs?

No - the CD4093BM96 inputs are CMOS and exhibit high impedance (>100 MΩ), so no pull-ups are needed unless the signal source is floating. When interfacing with open-collector or high-impedance sensors, a pull-up or pull-down may be used to define default state, but the Schmitt-trigger action itself does not depend on external biasing. The CD4093BM96 internal structure ensures defined thresholds regardless.

What is the meaning of the 'M96' suffix in CD4093BM96?

The 'M96' suffix in CD4093BM96 indicates the SOIC-14 package (M) supplied in large tape-and-reel format (96), specifically 2500 units per reel. This packaging variant is optimized for automated surface-mount assembly lines and differs from CD4093BM (50-unit tube) and CD4093BMT (obsolete SOIC tape). All 'M'-suffix variants share identical die, electrical specs, and pinout - only packaging and reel quantity differ.
