概述

Description

CD4093BCM is a CMOS quad 2-input NAND gate with Schmitt-trigger inputs. Key points:
- Four independent gates: 1A–1B → 1Y, 2A–2B → 2Y, 3A–3B → 3Y, 4A–4B → 4Y.
- Schmitt-trigger inputs give hysteresis for clean switching and good noise immunity.
- Supply voltage: typically 3 V to 18 V (CMOS 4000 family range).
- Output: standard CMOS push-pull; moderate drive capability (suits switching, buffering).
- Propagation delay: depends on supply and load (tens to hundreds of nanoseconds typical).
- Common uses: debouncing switches, RC oscillators, waveform shaping, level shifting, simple logic gating.
- Package: 14-pin device; BCM suffix denotes a small, RoHS-compliant surface-mount variant (often SOIC-14).
Note: Tie unused inputs to defined levels; avoid floating inputs for predictable behavior.

Features

CD4093BCM Features:
- Quad 2-input NAND gates with Schmitt-trigger inputs (4 independent gates)
- Wide supply range: 3 V to 15 V ( CMOS 4000 series )
- Schmitt-trigger inputs provide hysteresis for noise immunity and clean switching of slowly changing signals
- Low static power consumption (CMOS tech)
- CMOS push-pull outputs suitable for moderate loading and high fan-out
- Fast switching relative to CMOS standards; performance varies with VDD
- Available in standard 14-pin packages (DIP, SOIC, etc.) under BCM variant
Common uses: debouncing switches, simple oscillators, waveform shaping, and other logic-gating tasks requiring noisy-input tolerance.

Package

CD4093BCM is the 14‑pin small‑outline package (SOIC) version of the CD4093 (BCM = molded SOIC package).

Pinout

- Pin count: 14 pins (DIP-14 / SOP-14 variants)
- Function: CMOS Quad 2-input NAND gate with Schmitt-trigger inputs (four independent gates; each has inputs A and B and an output Y; Y = NOT(A AND B)). Power rails Vdd and Vss are provided.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a multinational American semiconductor company that designs and manufactures analog and digital integrated circuits, microcontrollers, sensors, and other semiconductor products for diverse markets (industrial, automotive, consumer, computing).

Application

CD4093BCM is a CMOS quad 2-input NAND Schmitt trigger. Common applications:
- Debouncing mechanical switches/relays
- RC-based oscillators and timing (astable/monostable)
- Waveform shaping and edge conditioning for slow/noisy signals
- Pulse shaping, edge detection, and noise immunity in digital interfaces
- Level restoration and simple logic gating in low-power circuits
