Product details

Overview

74HCT241D,652 from Nexperia is an octal buffer/line driver with 3-state outputs, designed for bus-oriented bidirectional data transmission in TTL-compatible systems. It features 2.0 V to 6.0 V supply voltage, ±4 mA output drive at V_CC = 4.5 V, and propagation delay of 19 ns typical at V_CC = 4.5 V. Used in microcontroller address/data bus interfacing and memory expansion circuits.

For engineers reviewing the 74HCT241D,652 datasheet, 74HCT241D,652 pinout, 74HCT241D,652 application, or 74HCT241D,652 equivalent, key selection criteria include 3-state control timing, TTL-level compatibility, bus hold capability absence, and SO16 package thermal performance in high-density PCB layouts.

Technical Context

This device implements two independent 4-bit non-inverting buffers, each controlled by a single active-low output-enable (OE) input. All inputs tolerate 5.5 V regardless of supply voltage, enabling mixed-voltage interface between 3.3 V logic and 5 V buses.

Output stages use standard CMOS push-pull circuitry with symmetrical rise/fall times (typ. 14 ns), and input hysteresis ensures noise immunity on OE and data lines. No internal pull-ups or bus-hold circuitry is integrated.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	HCT - TTL-compatible input thresholds with CMOS power efficiency
Supply Voltage Range	2.0 V to 6.0 V - supports dual-rail operation and legacy 5 V system integration
Propagation Delay	19 ns max at V_CC = 4.5 V - enables reliable timing in 25 MHz bus cycles
Output Drive	±4 mA at V_CC = 4.5 V - sufficient to drive 10 LSTTL loads or 20 pF capacitive bus
Input Voltage Tolerance	Up to 5.5 V - allows safe interfacing with higher-voltage peripherals without level shifters
Operating Temperature	−40 °C to +125 °C - qualified for industrial and automotive under-hood environments

Pinout & Package

Supplied in 16-pin SOIC (SO16) package, 3.9 mm body width, 1.27 mm pitch, with standard JEDEC MS-012AC footprint and 2.0 W thermal dissipation rating at 70 °C ambient.

Pin/Terminal	Circuit Role	Design Meaning
1A–4A, 1B–4B	Data inputs (two 4-bit groups)	Non-inverting input terminals for respective buffer channels; no internal termination
1Y–4Y, 5Y–8Y	3-state outputs (two 4-bit groups)	Active-high outputs disabled when OE low; high-impedance state leakage < 10 µA
1OE, 2OE	Active-low output enable	Independent control per 4-bit group; VIH ≤ 0.8 V, VIL ≥ 2.0 V at V_CC = 4.5 V
V_CC, GND	Power supply pins	Single-supply operation only; no separate ground for each port

Key Features

Feature	Design Value
CMOS power consumption	Static ICC < 2 µA at V_CC = 5 V - reduces standby current in battery-backed systems
TTL-compatible inputs	VIH = 2.0 V min, VIL = 0.8 V max - eliminates need for external level translators in 5 V designs
Overvoltage tolerant inputs	Withstands 5.5 V input signals at any V_CC from 2.0–6.0 V - prevents latch-up during hot-swap or mixed-voltage insertion
Specified 3-state timing	t_pd, t_PLZ, t_PZH all guaranteed over full temperature and voltage range - ensures deterministic bus release timing

Equivalent & Alternatives

The following parts are listed as comparable options for similar octal 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT241DR	TI SOIC-16 variant with identical AC/DC specs; slightly tighter t_PLH/t_PHL skew (±0.5 ns vs ±1.0 ns)	Same bus isolation role; validated in TI's MSP430FR59xx reference designs	Preferred where TI ecosystem toolchain support is required
74VHC241M	Lower drive (±8 mA), wider V_CC range (2–5.5 V), but no 5.5 V input tolerance	Not suitable for mixed-voltage interfaces; limited to 3.3 V–5 V-only systems	Select only when higher output current is needed and overvoltage protection is unnecessary

Compared with SN74HCT241DR and 74VHC241M, the 74HCT241D,652 uniquely balances 5.5 V input tolerance, industrial temperature range, and JEDEC-standard SO16 footprint-making it optimal for retrofitting legacy 5 V industrial controllers without redesigning PCB layout or adding protection circuitry.

FAQ

Can 74HCT241D,652 operate with a 3.3 V supply while interfacing with 5 V peripherals?

Yes. The device operates from 2.0 V to 6.0 V and features 5.5 V-tolerant inputs. At V_CC = 3.3 V, inputs accept 0–5.5 V signals without damage or level translation, making it suitable for mixed-voltage bus bridging in modern embedded systems.

Does 74HCT241D,652 include bus-hold or auto-direction sensing?

No. This device has no bus-hold circuitry or direction control logic. It is a fixed-function non-inverting buffer with independent active-low output-enable inputs per 4-bit group. Directionality must be managed externally via control signals.

What is the maximum capacitive load this device can drive reliably?

At V_CC = 4.5 V and T_A = 25 °C, the output can drive up to 20 pF while maintaining specified propagation delay and edge rates. For heavier loads (>30 pF), series termination or reduced slew rate may be required to avoid ringing.

Is 74HCT241D,652 pin-compatible with older 74LS241 devices?

Yes. It uses identical SO16 pinout and logic function mapping. However, HCT offers CMOS power efficiency, wider supply range, and improved noise margins versus LS, allowing direct replacement without circuit modification in most 5 V systems.
