Product details
Overview
CD40175BMT from Texas Instruments is a quad D-type flip-flop IC with independent clock and reset inputs per latch, 16-pin SOIC package, ±3V to ±18V supply range, propagation delay of 120 ns at 5 V, and operation from –55°C to +125°C - used in digital state storage, clocked register design, and synchronous logic control.
For engineers reviewing the CD40175BMT datasheet, CD40175BMT pinout, CD40175BMT application, or CD40175BMT equivalent, key selection criteria include supply voltage tolerance, latch independence, propagation delay consistency across channels, and compatibility with legacy CMOS logic families in industrial control and instrumentation systems.
Technical Context
The CD40175BMT implements four edge-triggered D-type latches sharing no internal signal paths - each has dedicated CLK and RESET pins, enabling asynchronous initialization and staggered sampling. Its dual-supply CMOS architecture supports rail-to-rail input thresholds and high noise immunity.
It operates across the full military temperature range (–55°C to +125°C) with guaranteed DC parameters at both extremes, and exhibits symmetrical rise/fall times under matched load conditions - critical for deterministic timing in multi-channel data capture circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | CMOS - ensures low static power consumption and high input impedance for minimal loading on driving stages. |
| Supply Voltage Range | ±3 V to ±18 V - supports wide-range analog-compatible digital interfacing and mixed-signal system integration. |
| Propagation Delay | 120 ns max at VDD = 5 V - defines maximum clock-to-output timing uncertainty in synchronous register chains. |
| Operating Temperature | –55°C to +125°C - qualified for extended-temperature industrial, aerospace, and downhole electronics applications. |
| Input Threshold | VDD/2 ± 0.5 V - provides predictable switching point across voltage rails, simplifying interface design with TTL or other CMOS devices. |
| Output Drive | ±4.2 mA at VDD = 15 V - sufficient to drive multiple 4000-series inputs or small capacitive loads without buffering. |
Pinout & Package
CD40175BMT uses a 16-pin SOIC (D) package measuring 9.9 mm × 3.91 mm × 1.75 mm, with standard JEDEC MO-153 outline and 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Data Input (D) | Independent D inputs for each of four latches - allows parallel data loading with separate control per channel. |
| 2, 6, 10, 14 | CLK Input | Positive-edge-triggered clock per latch - enables asynchronous sampling or phase-divided clocking schemes. |
| 3, 7, 11, 15 | RESET Input | Active-high asynchronous reset per latch - clears Q output independently without affecting other latches. |
| 4, 8, 12, 16 | Q Output | True output of corresponding latch - directly drives downstream logic or analog switches with rail-to-rail swing. |
| 16 (VDD), 8 (VSS) | Power Supply | Separate positive and negative supply pins - supports true dual-supply operation and bipolar logic level translation. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent D latches | Enables isolated register storage per channel - eliminates crosstalk and timing skew between functional blocks. |
| Dual-supply CMOS operation | Supports ±3 V to ±18 V supplies - allows direct interfacing with op-amps, ADCs, and analog front-ends without level shifters. |
| Asynchronous per-latch reset | Permits selective clearing of individual registers during runtime - essential for fault recovery and state machine reinitialization. |
| Military-grade temperature rating | Guaranteed functionality from –55°C to +125°C - meets MIL-PRF-38535 Class B requirements for harsh-environment deployment. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad D-type latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD40175BM96 | Same die, SOIC-16 tape-and-reel packaging (2500 pcs/reel), RoHS-compliant NIPDAU finish, MSL Level-1. | Preferred for high-volume automated assembly where reel-fed placement is required. | Select CD40175BM96 when production volume justifies tape-and-reel logistics and RoHS compliance is mandatory. |
| CD40175BPWR | Same die, TSSOP-16 package (12.0 mm × 4.4 mm × 1.2 mm), finer 0.65 mm pitch, lower profile. | Suitable for space-constrained PCB layouts where SOIC footprint is excessive. | Choose CD40175BPWR when board area is limited and reflow profile supports MSL Level-1 handling. |
Compared with CD40175BMT, CD40175BM96 offers identical electrical performance with optimized logistics for mass production, while CD40175BPWR trades package size for tighter layout constraints - neither requires schematic changes but demands updated land patterns and stencil designs.

FAQ
What is the function of CD40175BMT in digital circuits?
The CD40175BMT functions as a quad D-type flip-flop with independent clock and reset per latch, used for synchronous data storage, register staging, and state retention in industrial control and instrumentation. Each of its four latches in CD40175BMT operates autonomously, supporting flexible timing architectures without internal coupling.
Does CD40175BMT support single-supply operation?
Yes, CD40175BMT supports single-supply operation by connecting VSS to ground and using VDD as the positive rail - it functions correctly from 3 V to 18 V with standard CMOS input thresholds referenced to VDD/2. The CD40175BMT datasheet confirms this configuration is fully characterized.
What is the maximum clock frequency supported by CD40175BMT?
The CD40175BMT does not specify a maximum clock frequency in its datasheet; instead, timing is defined by minimum pulse width and propagation delay. At VDD = 15 V, the minimum clock pulse width is 60 ns, implying practical operation up to ~8 MHz in well-designed layouts - verified across all channels of the CD40175BMT under load conditions.
Is CD40175BMT pin-compatible with CD40175BE (PDIP package)?
Yes, CD40175BMT and CD40175BE share identical pinouts and electrical specifications - both use the same 16-pin configuration with D, CLK, RESET, and Q assignments. The only difference is package type: SOIC for CD40175BMT versus PDIP for CD40175BE - confirmed in TI's official package drawings and logic family documentation.
Why is CD40175BMT marked as Obsolete in TI's packaging addendum?
CD40175BMT is marked Obsolete because Texas Instruments discontinued SOIC-tube packaging for this variant; however, functionally identical versions like CD40175BM96 (SOIC tape-and-reel) remain active. The CD40175BMT silicon die and specifications are unchanged - only the packaging format and distribution channel were retired.
