Product details

Overview

CCBTLV3257MPWREP from Texas Instruments is a radiation-hardened, low-voltage 4-bit 1-of-2 FET multiplexer/demultiplexer designed for high-reliability signal routing in extended-temperature aerospace and defense systems. It features 5-Ω typical on-state resistance, rail-to-rail switching across 2.3 V to 3.6 V supply, I_off partial-power-down protection, and guaranteed operation from –55°C to 125°C.

For engineers reviewing the CCBTLV3257MPWREP datasheet, CCBTLV3257MPWREP pinout, CCBTLV3257MPWREP application, or CCBTLV3257MPWREP equivalent, this page delivers verified electrical specs, TSSOP-16 pin mapping, real-world use cases in MIL-PRF-38535-compliant systems, and two qualified alternative parts with documented functional and thermal differences.

Technical Context

The CCBTLV3257MPWREP implements four independent bilateral FET switches, each selectable between two data paths (B1/B2) via a common select (S) input. Each switch operates with minimal propagation delay (0.15 ns typical at 2.5 V) due to low on-resistance and optimized gate drive.

Control logic uses active-low output enable (OE) and single-bit select (S) to configure all four channels simultaneously. The device supports hot insertion and back-drive isolation via I_off, ensuring no current flows when V_CC = 0 V and inputs/outputs range from 0 to 3.6 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.3 V to 3.6 V - Ensures compatibility with 2.5 V and 3.3 V logic domains without level translation.
On-State Resistance (r_on)	5 Ω typical at V_CC = 2.5 V, I_I = 64 mA - Minimizes voltage drop and signal distortion in high-speed data paths.
Propagation Delay (t_pd)	0.15 ns typical at V_CC = 2.5 V - Enables sub-nanosecond switching for timing-critical bus multiplexing.
I_off Leakage Current	15 μA max at V_CC = 0 V - Prevents damaging back-current during partial power-down sequences.
Operating Temperature	–55°C to 125°C - Qualified per MIL-PRF-38535 for sustained operation in extreme environmental conditions.
ESD Protection	2000-V HBM, 200-V MM - Meets JESD22-A114/A115 for robust handling in production and field environments.
Latch-up Immunity	>100 mA per JESD78 Class II - Guarantees immunity to destructive latch-up under transient overvoltage events.

Pinout & Package

TSSOP-16 (PW package), 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant NiPdAu lead finish, MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	B1/B2 port terminals (8 total)	Four bidirectional B1 and B2 data pairs - each pair connects to A port when selected by S and OE.
9, 10, 11, 12	A port terminals (4)	Four bidirectional A-side data lines - routed to selected B1 or B2 path based on S input state.
13	GND	Ground reference for all internal circuitry and switch substrate bias.
14	V_CC	Primary power supply - powers internal logic and FET gates; must be stable before enabling OE.
15	OE	Active-low output enable - drives all four switches into high-impedance state when high.
16	S	Select control - determines whether A ports connect to B1 (S = L) or B2 (S = H) paths.

Key Features

Feature	Design Value
Rail-to-rail analog switching	Supports full-swing signals from GND to V_CC without clipping - critical for mixed-signal bus sharing.
I_off partial-power-down protection	Blocks current flow when V_CC = 0 V and I/O pins are biased - enables safe hot-swap and power sequencing.
Low 5-Ω on-resistance	Reduces insertion loss and maintains signal integrity in high-frequency data paths up to 200 MHz.
Extended temperature qualification	Validated from –55°C to 125°C per JEDEC and MIL-PRF-38535 - eliminates derating in harsh-environment designs.
High ESD and latch-up immunity	2000-V HBM / >100 mA latch-up rating - ensures reliability in handling, assembly, and deployed systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FET multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBTLV3257PWR	Commercial-grade (–40°C to 85°C), same pinout and r_on, but lacks MIL-PRF-38535 qualification and extended temp testing.	Not suitable for space or military platforms requiring radiation tolerance or >85°C operation.	Select only for cost-sensitive terrestrial industrial or test equipment where extended temp and DMS support are not required.
V62/08615-01XE	Identical die and PW package, same –55°C to 125°C rating, but certified to V62 Class V (enhanced screening for space).	Required for NASA Class V or DoD Category I programs demanding highest reliability screening beyond standard EP grade.	Choose when mission-critical applications mandate V62-level burn-in, lot acceptance testing, and radiation assurance documentation.

Compared with CCBTLV3257MPWREP, SN74CBTLV3257PWR sacrifices environmental robustness for lower cost, while V62/08615-01XE adds stringent screening overhead for ultra-high-reliability deployments - neither is pin-compatible without verifying board-level compliance with respective thermal and ESD design rules.

FAQ

What is the maximum operating frequency supported by the CCBTLV3257MPWREP?

The CCBTLV3257MPWREP does not specify a hard maximum frequency limit, but its 5-Ω on-resistance and 0.15 ns typical propagation delay enable reliable operation with digital signals up to 200 MHz and analog signals with bandwidths exceeding 100 MHz. Performance depends on load capacitance and PCB layout; for 30 pF loads, rise/fall times remain sub-nanosecond. The CCBTLV3257MPWREP is commonly used in high-speed bus multiplexing where signal integrity is preserved across full logic swings.

Does the CCBTLV3257MPWREP support hot-swap or live-insertion scenarios?

Yes, the CCBTLV3257MPWREP supports hot-swap operation through its I_off feature: when V_CC = 0 V, leakage remains ≤15 μA even if I/O pins are biased from 0 V to 3.6 V. This prevents back-current damage during insertion or removal in powered-backplane systems. The CCBTLV3257MPWREP also includes robust ESD protection (2000-V HBM), making it suitable for field-replaceable module designs in avionics and telecom infrastructure.

How does the CCBTLV3257MPWREP differ from the commercial SN74CBTLV3257PWR?

The CCBTLV3257MPWREP is an enhanced-product (EP) variant with full MIL-PRF-38535 qualification, extended –55°C to 125°C operation, controlled baseline manufacturing, and enhanced DMS support. In contrast, SN74CBTLV3257PWR is commercial-grade (–40°C to 85°C) with no radiation or extended-temp testing. Both share identical pinout and electrical specs at 25°C, but the CCBTLV3257MPWREP guarantees performance across the full military temperature range and offers long-term supply assurance.

Can the CCBTLV3257MPWREP be used with 1.8 V logic systems?

No - the CCBTLV3257MPWREP is specified only for 2.3 V to 3.6 V supply operation. At V_CC < 2.3 V, parameters including r_on, t_pd, and VIH/VIL thresholds are not guaranteed. For 1.8 V systems, TI recommends alternatives like SN74LVC1G3157 or SN74AUC2G66, which are characterized down to 1.65 V. The CCBTLV3257MPWREP must be operated within its recommended V_CC range to ensure rail-to-rail switching and I_off functionality.

What is the purpose of tying OE to V_CC through a pullup resistor during power-up?

Tying OE to V_CC via a pullup resistor ensures the CCBTLV3257MPWREP remains in high-impedance (disabled) state during power ramp-up, preventing undefined signal states or bus contention. The minimum resistor value depends on the driver's sink capability; TI recommends ≥10 kΩ for most microcontroller GPIOs. This practice avoids glitches on A/B ports until system firmware explicitly asserts OE low - a critical requirement for deterministic initialization in safety-critical CCBTLV3257MPWREP deployments.
