Product details
Overview
74HCT241PV-E from Renesas Electronics is an octal noninverting buffer/line driver with dual 3-state control (1G active-low, 2G active-high), designed for bidirectional bus interface and data routing in 5 V TTL-compatible digital systems. It delivers 10 ns typical propagation delay (CL = 50 pF), ±6 mA output drive, and operates across –40°C to +85°C. Used in industrial control backplanes and legacy instrumentation I/O expansion.
For engineers reviewing the 74HCT241PV-E datasheet, 74HCT241PV-E pinout, 74HCT241PV-E application, or 74HCT241PV-E equivalent, key selection criteria include guaranteed 4.5–5.5 V supply operation, LSTTL-level input compatibility, high-impedance 3-state outputs with independent enable control, and DIP-20 package mechanical compatibility with legacy socketed designs.
Technical Context
The 74HCT241PV-E implements two independent 4-bit buffer groups (1A1–1A4 and 2A1–2A4), each controlled by its own enable signal (1G and 2G). Outputs are noninverting and feature true 3-state logic - not open-drain or push-pull with weak pull-ups. No Schmitt-trigger inputs are included, requiring clean digital edges at the inputs.
It belongs to the 74HCT family, ensuring CMOS-level power efficiency while maintaining LSTTL voltage thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and fanout capability of 15 LSTTL loads. All timing parameters are specified under CL = 50 pF load conditions, with tPHL/tPLH ≤ 25 ns over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation in noisy 5 V rails without brownout or overvoltage risk |
| Propagation Delay | 9–11 ns typ (A→Y, CL = 50 pF) - supports >30 MHz bus toggle rates in synchronous interfaces |
| Output Drive | ±6 mA - sufficient to drive 15 LSTTL loads or terminate short PCB traces without external buffers |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable interfacing with standard TTL and 5 V CMOS logic families |
| Quiescent Current | 4 µA max (Ta = 25°C) - enables low-power standby in battery-backed or energy-sensitive subsystems |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade environments including factory automation and test equipment |
| Off-State Leakage | ±0.5 µA max (IOZ) - prevents unintended current paths when outputs are disabled in multiplexed bus architectures |
Pinout & Package
Dual-in-line package (DIP-20), 2.54 mm pitch, body width 6.3 mm, length 24.5 mm (RENESAS code DP-20NEV, JEITA PRDP0020AC-B). RoHS-compliant Ni/Pd/Au plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1G | Group 1 Output Enable (active low) | Controls high-impedance state for Y1–Y4 outputs; must be pulled low to enable 1A1–1A4 → 1Y1–1Y4 path |
| 2G | Group 2 Output Enable (active high) | Controls high-impedance state for Y5–Y8 outputs; must be driven high to enable 2A1–2A4 → 2Y1–2Y4 path |
| 1A1–1A4 | Group 1 Input | Noninverting inputs routed to 1Y1–1Y4 when 1G = L |
| 2A1–2A4 | Group 2 Input | Noninverting inputs routed to 2Y1–2Y4 when 2G = H |
| 1Y1–1Y4 | Group 1 Output | Buffered noninverting outputs of 1A1–1A4; high-Z when 1G = H |
| 2Y1–2Y4 | Group 2 Output | Buffered noninverting outputs of 2A1–2A4; high-Z when 2G = L |
| 10 | GND | Ground reference for all logic and power domains |
| 20 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| LSTTL-Compatible Inputs | VIH = 2.0 V min / VIL = 0.8 V max enables direct connection to legacy 74LS and 74F logic without level shifters |
| Dual Independent Enables | 1G (active-low) and 2G (active-high) allow asymmetric bus arbitration - e.g., one group enabled by microcontroller GPIO, other by system reset signal |
| Low Quiescent Power | ICC ≤ 4 µA static current reduces total system standby power in multi-buffer configurations |
| High Noise Immunity | Input hysteresis not present, but guaranteed VIH/VIL margins provide 1.2 V noise margin at VCC = 5 V |
| Robust Output Drive | ±6 mA sink/source capability eliminates need for external bus transceivers in point-to-point or lightly loaded stubbed buses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT241N | Identical logic function, timing, and DC specs; same DIP-20 package (Texas Instruments part number) | No functional difference; pinout and footprint identical to 74HCT241PV-E | Select when TI-sourced supply chain or dual-sourcing strategy is required |
| 74VHC241N | Higher speed (tPD = 5.5 ns typ), wider VCC range (2–5.5 V), but lower drive (±8 mA) and different input thresholds (VIH = 3.5 V min at VCC = 5 V) | Not suitable for direct LSTTL interface without level translation due to higher VIH requirement | Choose only if system uses mixed 3.3 V/5 V logic and requires faster propagation - verify input compatibility first |
Compared with SN74HCT241N, the 74HCT241PV-E offers identical functionality and drop-in replacement capability; versus 74VHC241N, it provides guaranteed LSTTL interoperability at the cost of slightly higher propagation delay, making it the preferred choice for legacy 5 V TTL system integration.

FAQ
What is the maximum operating temperature range for the 74HCT241PV-E?
The 74HCT241PV-E is rated for operation from –40°C to +85°C, meeting industrial-grade environmental requirements. This range is validated per Renesas' Recommended Operating Conditions and confirmed in the Absolute Maximum Ratings table. The device maintains full electrical performance-including propagation delay, output drive, and 3-state leakage-across this entire span, making it suitable for factory-floor controllers and outdoor test instrumentation where ambient temperatures fluctuate widely. Always ensure adequate PCB thermal relief and avoid exceeding 500 mW total power dissipation.
Does the 74HCT241PV-E have Schmitt-trigger inputs?
No, the 74HCT241PV-E does not include Schmitt-trigger inputs. Its input stage uses standard CMOS threshold detection with VIH = 2.0 V min and VIL = 0.8 V max at VCC = 5 V, providing a fixed 1.2 V noise margin but no hysteresis. This means slow-rising or noisy input signals may cause metastability or multiple switching events. For such cases, external RC filtering or dedicated Schmitt-trigger buffers (e.g., 74HCT14) should precede the 74HCT241PV-E inputs. The absence of hysteresis is explicitly stated in the original Renesas datasheet Rev.2.00.
What is the pinout compatibility between 74HCT241PV-E and SN74HCT241N?
The 74HCT241PV-E and SN74HCT241N share identical pinout, function table, and DIP-20 mechanical dimensions (2.54 mm pitch, 6.3 × 24.5 mm body). Both devices implement the same dual-group 3-state buffer architecture with 1G (pin 1, active-low) and 2G (pin 2, active-high) enables, and matching input/output assignments across pins 2–9 and 11–18. This allows direct physical and functional substitution without PCB modification, provided both are operated within their respective 4.5–5.5 V supply and –40°C to +85°C temperature specifications.
Can the 74HCT241PV-E drive a 50 pF load with guaranteed timing?
Yes, the 74HCT241PV-E's switching characteristics-including tPLH, tPHL, tZL, and tZH-are fully characterized and guaranteed at CL = 50 pF, as defined in the "Switching Characteristics" table of the Renesas datasheet. At VCC = 4.5 V and Ta = 25°C, tPLH/tPHL are 9/11 ns typical and ≤25 ns maximum over full temperature range. To maintain these specs, ensure PCB trace capacitance plus probe/jig capacitance stays at or below 50 pF; use proper grounding, minimize stub lengths, and avoid floating nodes near outputs. Exceeding CL degrades timing predictably but violates published specs.
Is the 74HCT241PV-E RoHS compliant?
Yes, the 74HCT241PV-E is RoHS compliant, using Ni/Pd/Au plating on its leads as confirmed in the "Package Dimensions" section of the Renesas datasheet Rev.2.00. This plating meets EU Directive 2011/65/EU requirements for restricted substances, including lead content below 0.1 wt%. The device carries no exemption codes and is classified as "lead-free" in Renesas' official product documentation. For full compliance verification, refer to Renesas' material declarations available via their website or authorized distributor portals.
