Product details

Overview

74LVCH244AD,112 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver with 5V-tolerant inputs and outputs, operating from 1.2V to 3.6V supply, featuring ±24mA drive strength and 3.8ns typical propagation delay at V_CC = 3.3V. It enables bidirectional data buffering in low-voltage industrial control backplanes.

For engineers reviewing the 74LVCH244AD,112 datasheet, 74LVCH244AD,112 pinout, 74LVCH244AD,112 application, or 74LVCH244AD,112 equivalent, key selection criteria include voltage-level translation capability, bus-hold functionality, output drive strength, and 3-state timing compatibility with legacy 5V logic interfaces.

Technical Context

This device integrates eight independent non-inverting buffers, each with separate 3-state enable controls (1OE, 2OE) for dual 4-bit group operation. All inputs tolerate up to 5.5V regardless of supply voltage, enabling mixed-voltage system interfacing without external level shifters.

Each output supports 3-state operation with high-impedance disable, bus-hold circuitry to prevent floating inputs, and ESD protection exceeding 4kV HBM. Propagation delay is specified from 1.2V to 3.6V across industrial temperature range (−40°C to +125°C).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2V to 3.6V - Enables direct integration into 1.8V and 3.3V systems while maintaining 5V-tolerant I/O
Input Voltage Tolerance	Up to 5.5V - Allows safe connection to 5V buses without external clamping or translation
Output Drive Strength	±24mA at V_CC = 3.3V - Sufficient to drive standard TTL loads and short PCB traces without signal degradation
Propagation Delay	3.8ns typical at V_CC = 3.3V - Supports >100MHz bus operation in synchronous data transfer applications
Bus-Hold Input Circuitry	Integrated on all inputs - Eliminates need for external pull-up/down resistors on unused or unterminated lines
ESD Protection	≥4kV HBM - Meets industrial IEC 61000-4-2 surge immunity requirements for board-level robustness

6–9, 12–15	Data Outputs (1Y1–1Y4, 2Y1–2Y4)	3-state CMOS outputs with ±24mA drive; high-impedance when OE is high
10	GND	Ground reference for all internal logic and I/O circuits
20	V_CC	Primary power supply input (1.2V–3.6V); powers internal logic and output drivers

Key Features

Feature	Design Value
5V-tolerant inputs and outputs	Enables seamless interface between 3.3V/1.8V logic domains and legacy 5V subsystems without external components
Bus-hold circuitry on all inputs	Prevents undefined logic states on floating or unterminated inputs, reducing BOM count and layout complexity

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC244APWR	Same 1.65V–3.6V V_CC range but lacks 5V-tolerant inputs; requires external level shifting for 5V interfaces	Not suitable for mixed-voltage backplane use where 5V signals are present	Select only if entire system operates strictly within 1.65V–3.6V and no 5V signal coupling occurs
74ALVC244MTCX	Higher speed (2.5ns t_PD) but narrower V_CC range (2.3V–3.6V); no bus-hold circuitry	Requires external pull resistors on unused inputs; incompatible with 1.8V-only or 1.2V systems	Prefer for high-speed timing-critical paths where voltage margin is guaranteed ≥2.3V

Compared with SN74LVC244APWR and 74ALVC244MTCX, the 74LVCH244AD,112 uniquely combines 1.2V operation, 5V tolerance, and integrated bus-hold-making it the only choice for robust, low-voltage, mixed-signal industrial backplanes.

FAQ

What is the maximum input voltage the 74LVCH244AD,112 can safely accept?

The device accepts input voltages up to 5.5V on all pins, independent of V_CC level. This 5V tolerance is achieved via internal clamp diodes and is fully characterized across −40°C to +125°C. No external protection is required when interfacing with 5V logic families, even when powered from 1.2V or 1.8V supplies.

Does the 74LVCH244AD,112 require external pull-up or pull-down resistors?

No. All inputs feature integrated bus-hold circuitry that actively maintains the last valid logic state when un-driven, eliminating the need for external biasing resistors. This reduces PCB area, BOM cost, and potential noise coupling from resistor networks on high-density layouts.

Can the 74LVCH244AD,112 drive standard TTL loads directly?

Yes. With ±24mA output drive capability at V_CC = 3.3V, it meets or exceeds the current requirements of standard TTL (74LS) inputs (I_IL = −0.4mA, I_IH = 20µA). Output voltage levels remain within TTL-compatible thresholds across full load and temperature range.

Is the 74LVCH244AD,112 pin-compatible with older 74HC244 devices?

No. While functionally similar, the 74LVCH244AD,112 uses SO20 packaging with different pin assignments than the PDIP20 or TSSOP20 variants of 74HC244. Specifically, enable pins (1OE/2OE) are located on pins 1 and 19, whereas 74HC244 places them on pins 1 and 19 only in SO20 - but electrical behavior differs due to bus-hold and 5V tolerance not present in HC variants.
