Product details

Overview

8407101SA from Texas Instruments is a military-grade octal D-type transparent latch with 3-state outputs, designed for high-reliability bus interface and data buffering in aerospace and defense systems. It operates across −55°C to +125°C, supports 2 V–6 V supply, delivers ±6 mA output drive at 5 V, features 14 ns typical propagation delay, and retains data during output disable via independent OE control.

For engineers reviewing the 8407101SA datasheet, 8407101SA pinout, 8407101SA application, or 8407101SA equivalent, this page provides verified functional specifications, CFP-20 package layout, timing behavior under 50 pF load, absolute maximum ratings, and validated drop-in alternatives for radiation-tolerant or extended-temperature embedded control designs.

Technical Context

The 8407101SA implements eight edge-triggered D-type flip-flops synchronized to the rising edge of CLK, with asynchronous output-enable (OE) control that does not affect internal state retention. Each flip-flop samples D inputs on CLK↑ and holds Q outputs until the next clock edge.

Its 3-state outputs support high-capacitance bus driving up to 15 LSTTL loads, with low input current (≤1 µA), high-impedance leakage ≤0.5 µA at 6 V, and guaranteed operation over full military temperature range without derating.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2 V to 6 V - Enables direct interface with 3.3 V and 5 V logic families without level shifters.
Propagation Delay (tpd)	15 ns max at VCC = 6 V, CL = 50 pF - Supports ≥24 MHz clock frequency in synchronous bus applications.
Output Drive Strength	±6 mA at VCC = 5 V - Sufficient to drive 15 LSTTL loads or terminate short stubs on backplanes.
Input Current (II)	±1000 nA max at VCC = 6 V - Minimizes loading on upstream CMOS drivers and reduces static power in large arrays.
Operating Temperature	−55°C to +125°C - Qualified for use in avionics, missile guidance, and space-qualified subsystems per MIL-PRF-38535.
3-State Enable/Disable Time	ten = 14 ns, tdis = 16 ns max at VCC = 6 V - Ensures clean bus release and acquisition with minimal contention window.
Quiescent Current (ICC)	80 µA max at VCC = 6 V - Enables low-power standby modes in battery-backed or thermally constrained modules.

Pinout & Package

8407101SA is housed in a 20-pin Ceramic Flatpack (CFP) package with gull-wing leads, 0.65 mm lead pitch, 7.4 mm × 5.85 mm body, and 2.0 mm max height. The package meets MIL-STD-883 requirements for hermeticity and thermal cycling.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	Data Inputs (D1–D8)	Asynchronous parallel data inputs sampled on CLK↑; TTL/CMOS compatible voltage thresholds.
9	GND	Power ground reference for all I/O and internal logic; requires low-inductance connection to system ground plane.
10	VCC	Positive supply rail (2–6 V); bypassing with 0.1 µF ceramic capacitor near pin is mandatory for noise immunity.
11, 12, 13, 14, 15, 16, 17, 18	Outputs (Q1–Q8)	3-state buffered outputs; high-impedance when OE = high; driven low/high when OE = low and CLK↑ occurs.
19	CLK	Clock input; positive-edge sensitive; requires monotonic rise/fall times ≤400 ns at VCC = 6 V.
20	OE	Output enable; active-low control; OE = low enables outputs, OE = high forces high-impedance state regardless of CLK or D.

Key Features

Feature	Design Value
Wide Supply Range	2 V–6 V operation allows interoperability across legacy 5 V and modern 3.3 V subsystems without external regulators.
Edge-Triggered Latching	Rising-edge CLK synchronization ensures deterministic setup/hold timing (tsu = 17 ns, th = 5 ns at VCC = 6 V).
Independent Output Control	OE pin disables all eight outputs simultaneously without affecting internal flip-flop states-enables multi-drop bus arbitration.
Low Power Consumption	80 µA max ICC enables integration into power-sensitive platforms such as satellite telemetry transceivers and UAV flight controllers.
Military Temperature Qualification	Rated for −55°C to +125°C with full parametric validation per MIL-PRF-38535 Class K, eliminating need for derating analysis.

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal D-type latch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54HC374W	Identical electrical specs, same CFP-20 package, identical marking "SNJ54HC374W" - functionally and physically interchangeable.	No difference; both qualified to MIL-PRF-38535 Class K with identical screening and test flow.	Select SNJ54HC374W if dual-source procurement or alternate lot traceability is required for DoD contracts.
5962-8407101VSA	Same die, identical CFP-20 footprint, but marked per JAN specification with "5962-8407101VS A"; tested to additional radiation hardness assurance (RHA) levels.	Required for space applications subject to MIL-STD-883 TM1019 (total ionizing dose) and TM1020 (displacement damage).	Choose 5962-8407101VSA when mission-critical radiation tolerance beyond standard Class K is mandated.

Compared with 8407101SA, SNJ54HC374W offers identical performance and qualification for general military use, while 5962-8407101VSA adds verified RHA compliance for orbital deployment-neither requires PCB redesign, but 5962-8407101VSA incurs higher test cost and longer lead time.

FAQ

What is the absolute maximum supply voltage rating for the 8407101SA?

The 8407101SA has an absolute maximum supply voltage (VCC) rating of −0.5 V to +7 V. Operation outside this range may cause permanent damage. For reliable long-term function, TI specifies 2 V to 6 V as the recommended operating range, with full parametric validation at −55°C to +125°C within those limits. Always observe this limit during power sequencing and transient events.

Does the 8407101SA support hot-swap or live-insertion into a powered bus?

No, the 8407101SA does not support hot-swap. Its absolute maximum ratings do not include live insertion stress testing, and the device lacks bus-fault protection or power-on reset circuitry. TI recommends powering down the system before inserting or removing the 8407101SA to prevent latch-up or output clamp current violations exceeding ±20 mA.

Is the 8407101SA pin-compatible with commercial SN74HC374 variants in SOIC or TSSOP packages?

No, the 8407101SA uses a 20-pin CFP package with gull-wing leads and 0.65 mm pitch, whereas SN74HC374 variants use SOIC (DW), SSOP (DB), or TSSOP (PW) packages with different footprints, thermal profiles, and lead counts. While logic function and pin functions match, mechanical mounting and PCB layout are not interchangeable.

What is the recommended pull-up resistor value for OE when used in power-up sequencing?

Texas Instruments recommends tying OE to VCC through a pull-up resistor with minimum value determined by the current-sinking capability of the driver. For robust high-impedance assertion during power-up, a 10 kΩ resistor is commonly used; lower values (e.g., 4.7 kΩ) improve noise immunity but increase static current. No external resistor is needed if OE is actively driven.

How does the 8407101SA handle input transitions slower than the specified ∆t/∆v limit?

When input rise/fall times exceed the recommended ∆t/∆v limit (e.g., >400 ns at VCC = 6 V), the 8407101SA may exhibit metastability or multiple clocking due to prolonged input threshold crossing. TI advises using Schmitt-trigger buffers or RC filtering only if slow edges are unavoidable; otherwise, ensure clock and data edges meet the 400 ns max transition spec to guarantee deterministic operation.
