Product details
Overview
74HC241PV-E from Renesas Electronics is an octal noninverting buffer/line driver with dual 3-state enable controls (1G active-low, 2G active-high), designed for bidirectional bus interfacing and data routing in 2–6 V digital systems. It delivers 11 ns typical propagation delay (CL = 50 pF), ±35 mA output drive, and supports industrial temperature range (–40°C to +85°C) - used in programmable logic controllers, industrial I/O modules, and legacy bus interface circuits.
For engineers reviewing the 74HC241PV-E datasheet, 74HC241PV-E pinout, 74HC241PV-E application, or 74HC241PV-E equivalent, key selection criteria include its dual independent 4-bit enable architecture, high fanout (15 LSTTL loads), low quiescent ICC (4 µA max), and SOP-20 package compatibility with JEITA PRSP0020DD-B footprint.
Technical Context
The 74HC241PV-E implements two independent 4-bit noninverting buffer groups, each controlled by a dedicated enable input (1G for channels 1–4, 2G for channels 5–8). Its 3-state outputs support bus-sharing without external pull-ups or direction control logic.
It operates across 2.0–6.0 V supply range with TTL-compatible input thresholds (VIH = 1.5 V min at VCC = 2.0 V; VIL = 0.5 V max), and exhibits symmetrical tPLH/tPHL propagation delays (12 ns typ at VCC = 4.5 V, CL = 50 pF), ensuring predictable timing in mixed-voltage system interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | 11 ns typical (CL = 50 pF, VCC = 4.5 V) - supports >20 MHz bus operation in synchronous designs. |
| Output Drive Current | ±35 mA per output - drives heavy capacitive loads or multiple LSTTL inputs without buffering. |
| Input Leakage Current | ±0.1 µA max (VCC = 6.0 V) - negligible loading on upstream drivers, critical for low-power battery-backed circuits. |
| Quiescent Supply Current | 4.0 µA max (Ta = 25°C) - suitable for always-on monitoring nodes where standby power must be minimized. |
| Operating Temperature | –40°C to +85°C - qualified for industrial automation, factory-floor HMI, and outdoor control enclosures. |
| 3-State Enable Logic | 1G (active-low), 2G (active-high) - allows independent gating of two 4-bit data lanes using complementary control signals. |
Pinout & Package
SOP-20 package (JEITA PRSP0020DD-B, Renesas code FP-20DAV), 12.6 mm × 7.5 mm body, 1.27 mm pitch, gull-wing leads, Ni/Pd/Au plating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1G (Group 1 Enable) | Active-low control for buffers 1Y1–1Y4; asserts low to enable outputs, high to place in high-impedance state. |
| 2–5 | 1A1–1A4 (Group 1 Inputs) | Noninverting inputs for first four buffers; directly routed to corresponding 1Y outputs when 1G = L. |
| 6–9 | 2Y4–2Y1 (Group 2 Outputs) | Noninverting outputs for second four buffers; driven only when 2G = H; otherwise high-Z. |
| 10 | GND | Ground reference for all internal logic and output stages; requires low-inductance connection to minimize switching noise. |
| 11 | VCC | Positive supply rail (2–6 V); decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 12 | 2G (Group 2 Enable) | Active-high control for buffers 2Y1–2Y4; asserts high to enable, low to disable into high-impedance. |
| 13–16 | 1Y1–1Y4 (Group 1 Outputs) | Noninverting outputs for first four buffers; mirror 1A1–1A4 when 1G = L; high-Z when 1G = H. |
| 17–20 | 2A4–2A1 (Group 2 Inputs) | Noninverting inputs for second four buffers; routed to 2Y4–2Y1 respectively when 2G = H. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4-bit enables | Enables time-multiplexed bus sharing between two subsystems (e.g., CPU and FPGA) without arbitration logic. |
| High fanout (15 LSTTL) | Drives full TTL bus load without intermediate buffers, reducing component count and board area in legacy designs. |
| Wide VCC range (2–6 V) | Supports mixed-supply systems: interfaces 3.3 V microcontrollers to 5 V peripherals without voltage translation ICs. |
| Low ICC (4 µA max) | Minimizes standby current in always-powered industrial controllers, extending backup battery life in supervisory circuits. |
| No Schmitt-trigger inputs | Requires clean, monotonic input edges; mandates proper PCB layout and source impedance control to avoid metastability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal noninverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC241N | Same logic function, identical pinout, but PDIP-20 package (not SOP); higher parasitic inductance limits >10 MHz use. | Preferred for through-hole prototyping or legacy DIP-based systems; unsuitable for space-constrained SMT layouts. | Select SN74HC241N only when manual assembly or socket-based testing is required; 74HC241PV-E is optimal for automated SMT production. |
| 74HCT241PW | TTL-input thresholds (VIH = 2.0 V min), not HC-compatible; otherwise identical SOP-20 pinout and timing. | Better suited for direct interface with 5 V TTL sources; incompatible with 3.3 V-only microcontrollers lacking TTL tolerance. | Choose 74HCT241PW when driving from legacy 5 V TTL logic; retain 74HC241PV-E for mixed 3.3/5 V systems with CMOS-level sources. |
Compared with SN74HC241N and 74HCT241PW, the 74HC241PV-E uniquely balances SMT manufacturability, wide VCC flexibility, and true CMOS input compatibility - making it the preferred choice for new industrial control designs requiring long-term component availability and RoHS-compliant packaging.

FAQ
What is the maximum operating frequency supported by the 74HC241PV-E?
The 74HC241PV-E does not specify a maximum clock frequency, but its 11 ns typical propagation delay (at VCC = 4.5 V, CL = 50 pF) supports reliable operation up to approximately 20 MHz in well-terminated bus applications. Actual usable frequency depends on load capacitance, PCB trace length, and output transition requirements - design validation with worst-case tPHL/tPLH (23 ns max at –40°C to +85°C) is recommended for timing-critical systems using the 74HC241PV-E.
Does the 74HC241PV-E support 3.3 V logic levels?
Yes, the 74HC241PV-E fully supports 3.3 V operation: its VCC range includes 3.3 V, and input thresholds scale accordingly (VIH ≥ 2.1 V, VIL ≤ 1.2 V at VCC = 3.3 V per interpolation from datasheet VIH/VIL tables). Outputs swing rail-to-rail, delivering true 3.3 V logic levels - making the 74HC241PV-E suitable for interfacing 3.3 V microcontrollers to 5 V peripherals without level shifters.
What is the meaning of "PV-E" in the part number 74HC241PV-E?
The "PV-E" suffix in 74HC241PV-E denotes Renesas' standardized package and environmental coding: "P" indicates plastic package, "V" specifies SOP-20 (JEITA PRSP0020DD-B), and "E" signifies lead-free, RoHS-compliant construction with Ni/Pd/Au terminal plating. This matches the FP-20DAV package variant documented in the HD74HC241 datasheet Rev. 2.00, confirming the 74HC241PV-E as a surface-mount, environmentally compliant version of the HD74HC241.
Can the 74HC241PV-E replace a 74LS241 in an existing design?
Yes, the 74HC241PV-E is a functional and pin-compatible replacement for the 74LS241 in most cases: same pinout, identical logic function, and compatible 3-state behavior. However, note that the 74HC241PV-E draws significantly less supply current (4 µA vs. ~20 mA) and has faster propagation delay (11 ns vs. ~25 ns), which may require verifying setup/hold timing margins. Also, ensure VCC is within 2–6 V - unlike the 74LS241's fixed 5 V requirement - when substituting the 74HC241PV-E.
Is the 74HC241PV-E rated for automotive applications?
No, the 74HC241PV-E is classified as a Standard-grade Renesas product, qualified for industrial applications (–40°C to +85°C) but not for automotive use. It lacks AEC-Q100 qualification, extended temperature screening, or automotive-specific reliability testing. For automotive applications, Renesas offers separate AEC-Q100 qualified variants - the 74HC241PV-E should only be used in non-safety-critical industrial, commercial, or consumer equipment per Renesas' quality grade definitions.
