Details
General DescriptionThe MM74C914 is a monolithic CMOS Hex Schmitt trigger with special input protection scheme. This scheme allows the input voltage levels to exceed VCC or ground by at least 10V (VCC −25V to GND + 25V), and is valuable for applications involving voltage level shifting or mismatched power supplies.The positive and negative-going threshold voltages, VT+ and VT−, show low variation with respect to temperature (typ 0.0005V/°C at VCC = 10V). And the hysteresis, VT+ − VT− ≥ 0.2 VCC is guaranteed.Features■ Hysteresis: 0.45 VCC (typ.) 0.2 VCCguaranteed■ Special input protection: Extended Input Voltage Range■ Wide supply voltage range: 3V to 15V■ High noise immunity: 0.7 VCC (typ.)■ Low power TTL compatibility: Fan out of 2 driving 74L

FAQs
What is MM74C914N?
The MM74C914N is a 8-bit addressable latch with 3-state outputs designed by National Semiconductor. It is used for temporary data storage and output control in digital applications.
How Does MM74C914N Work?
The MM74C914N works by latching and storing 8-bit data based on the address inputs. It can then enable or disable the 3-state output buffers to control the data flow to the output pins. This allows for efficient data transfer and sharing in digital circuits.
How Many Pins does MM74C914N have and What are the Functions of the Pinout Configuration?
The MM74C914N is housed in a 16-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- A0-A2: Address input pins for selecting the latch.
- D0-D7: Data input/output pins for 8-bit data.
- OE: Output Enable pin to control the output buffer.
- CLK: Clock input for latching data.
- GND, VCC: Ground and power supply pins, respectively.
What are the Pros and Cons of MM74C914N?
Pros:
- Addressable Latch: Allows selective storage and retrieval of 8-bit data.
- 3-State Outputs: Enables easy control of data flow to output pins.
- Straightforward Operation: Simple clock and address inputs make it easy to interface with digital systems.
- Versatile Usage: Useful for applications requiring temporary data storage and output control.
- Industry Standard Package: 16-pin DIP package is widely accepted and easy to work with.
Cons:
- Limited Data Width: Supports 8-bit data only, which may be insufficient for some applications.
- No Built-In Error Detection: Does not provide error checking or correction capabilities.
- Power Consumption: Continuous clocking and use of 3-state outputs may consume more power in certain scenarios.
Are There Any Equivalents/Alternatives to MM74C914N for Recommendation?
- The CD74HC259E from Texas Instruments is a similar 8-bit addressable latch with 3-state outputs.
- Alternatives to the MM74C914N include the SN74LS259 from Texas Instruments and the 74HC573 from NXP Semiconductors.
