Product details
Overview
74ABT541PW,112 from NXP Semiconductors (formerly Philips) is an octal 3-state buffer/line driver in TSSOP20 package, operating from 4.5 V to 5.5 V, with 2.9 ns typical propagation delay (An→Yn), ±32 mA high-level and 64 mA low-level output drive, and designed for bus interface in industrial control and embedded data-path systems.
For engineers reviewing the 74ABT541PW,112 datasheet, 74ABT541PW,112 pinout, 74ABT541PW,112 application, or 74ABT541PW,112 equivalent, key selection criteria include 3-state enable timing (tPZH/tPLZ ≤ 6.4 ns), input/output capacitance (CIN = 4 pF, COUT = 7 pF), power-up 3-state behavior, latch-up immunity (>500 mA), and compatibility with 5 V TTL logic families.
Technical Context
The 74ABT541PW,112 implements a dual-enable octal buffer architecture with independent OE0 and OE1 controls enabling two groups of four outputs each. Its BiCMOS process delivers high-speed switching while maintaining MOS-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V) and robust DC output capability.
It supports live insertion/extraction and features power-off leakage current < ±100 µA, ICCZ = 500 nA at VCC = 5.5 V with outputs disabled, and operates across –40°C to +85°C with guaranteed AC performance under CL = 50 pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and CMOS systems without level-shifting. |
| Propagation Delay | 2.9 ns typical (An→Yn, CL = 50 pF) - Enables sub-350 MHz bus operation in synchronous data paths. |
| Output Drive | Sinks 64 mA / sources 32 mA - Drives heavy capacitive loads and multiple TTL inputs without external buffers. |
| Input Capacitance | 4 pF - Minimizes signal loading on upstream drivers and preserves edge integrity in high-speed routing. |
| 3-State Enable Time | tPZH ≤ 6.4 ns (max, –40°C to +85°C) - Supports tight timing budgets in multiplexed address/data bus applications. |
| ESD Protection | 2000 V HBM, 200 V MM - Meets industrial handling requirements without additional protection circuitry. |
| Latch-up Immunity | >500 mA per JESD78 - Guarantees robustness against transient ground bounce or supply rail faults. |
Pinout & Package
74ABT541PW,112 is housed in a 20-pin plastic thin shrink small outline package (TSSOP20, SOT360-1), 4.4 mm body width, 0.65 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 19 | OE0, OE1 | Independent active-low 3-state enables for A0–A3/Y0–Y3 and A4–A7/Y4–Y7 groups - allows partial bus gating without full device disable. |
| 2–9 | A0–A7 | Unidirectional data inputs - placed on left side for orthogonal PCB layout with output traces on right side. |
| 11–18 | Y0–Y7 | 3-state buffered outputs - capable of driving 64 mA sink / 32 mA source into terminated or unterminated lines. |
| 10 | GND | Ground reference - shared return path for all I/O and supply currents; requires low-inductance connection. |
| 20 | VCC | +5 V supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Octal 3-state buffering | Enables bidirectional bus sharing by isolating driven segments during contention or idle cycles. |
| Dual independent output enables | Permits selective activation of upper/lower nibbles (Y0–Y3 vs Y4–Y7), reducing dynamic power in partial-width transfers. |
| Power-up 3-state | Outputs remain high-impedance until VCC stabilizes above threshold - prevents bus contention during power sequencing. |
| Live insertion/extraction support | Allows hot-swap replacement in backplane or modular systems without system shutdown or reset. |
| BiCMOS process technology | Combines CMOS input stage (low leakage, high noise margin) with bipolar output stage (high drive, fast switching). |
Applications
| Industrial PLC Backplane Interface | Embedded Microprocessor Address Bus Driver |
|---|---|
Use Scenario: Driving parallel address/data buses between CPU and I/O modules in programmable logic controllers with mixed-voltage subsystems. IC Role / Device Role / Timing Role: Unidirectional buffer isolating microprocessor address lines from noisy field-side peripherals while meeting strict setup/hold timing. Use Value: 2.9 ns propagation delay and 64 mA sink capability ensure reliable signal integrity across 20 cm backplane traces at 25 MHz clock rates. |
Use Scenario: Expanding GPIO drive strength for legacy 8051 or Z80-based control boards requiring direct memory-mapped peripheral access. IC Role / Device Role / Timing Role: Level-translating and fan-out amplifying address latches before connecting to multiple EPROM or RAM chips. Use Value: Dual OE pins allow interleaved addressing of two memory banks without bus contention, reducing external logic count. |
| Test Equipment Signal Routing Matrix | Automated Test Fixture Data Path Isolation |
Use Scenario: Configurable signal routing in benchtop ATE systems where DUT signals must be dynamically connected to measurement instruments. IC Role / Device Role / Timing Role: 3-state switch element enabling software-controlled path selection between stimulus and response channels. Use Value: Live insertion support permits module replacement during calibration without powering down entire test rack. |
Use Scenario: Isolating production test fixtures from host controller during firmware updates or fault recovery sequences. IC Role / Device Role / Timing Role: Output gate preventing erroneous commands from propagating to actuators during boot or reset states. Use Value: Power-up 3-state behavior guarantees default isolation, eliminating need for external pull-up/pull-down networks. |
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 |
|---|---|---|---|
| SN74ABT244N | 8-bit non-inverting buffer with single OE (vs dual OE in 74ABT541PW,112); identical voltage/current specs and AC timing. | Requires external logic to split enable control if nibble-level gating is needed; otherwise drop-in for full-bus use cases. | Select when simplified enable architecture suffices and PCB layout favors DIP-20 or SOIC-20 packages. |
| 74LVT244PW | Lower VCC range (2.7–3.6 V), 3.3 V logic compatible; tPLH = 3.1 ns (slower), IOH = ±24 mA (reduced drive). | Not suitable for 5 V systems; used only where LVT family's lower power and 3.3 V compatibility are mandatory. | Choose only for 3.3 V mixed-signal designs where 74ABT541PW,112's 5 V operation is incompatible. |
Compared with SN74ABT244N and 74LVT244PW, the 74ABT541PW,112 uniquely provides dual independent output enables in a 5 V, high-drive, TSSOP20 form factor-making it optimal for space-constrained industrial backplanes requiring partial bus control without added glue logic.

FAQ
What is the maximum operating temperature range for the 74ABT541PW,112?
The 74ABT541PW,112 is rated for continuous operation from –40°C to +85°C ambient temperature. This range is validated per the manufacturer's recommended operating conditions and applies to all electrical and timing specifications in the datasheet, including propagation delay and output drive capability under full load.
Does the 74ABT541PW,112 support live insertion and extraction?
Yes, the 74ABT541PW,112 supports live insertion and extraction as confirmed in its official Philips product specification. This capability is enabled by its BiCMOS design, power-up 3-state behavior, and robust ESD/latch-up protection-allowing safe hot-swap in modular backplane or test fixture applications without system interruption.
What is the function of pins 1 and 19 on the 74ABT541PW,112?
Pins 1 and 19 are OE0 and OE1-active-low output enable terminals controlling separate groups of four outputs (Y0–Y3 and Y4–Y7). When both are low, all eight outputs are enabled; if either is high, its corresponding group enters high-impedance state. This dual-enable structure is intrinsic to the 74ABT541PW,112 and enables flexible bus segmentation.
Can the 74ABT541PW,112 drive standard TTL loads directly?
Yes, the 74ABT541PW,112 can drive standard TTL loads directly: its 64 mA sink and 32 mA source capability exceeds the worst-case TTL input current requirements (IIL = –1.6 mA, IIH = 40 µA), and its VOH ≥ 2.4 V and VOL ≤ 0.55 V meet TTL voltage thresholds across the full operating temperature range.
Is the 74ABT541PW,112 pin-compatible with the 74ABT244?
No, the 74ABT541PW,112 is not pin-compatible with the 74ABT244. While both are octal 3-state buffers, the 74ABT541PW,112 uses dual OE pins (pins 1 and 19) and separates inputs (pins 2–9) from outputs (pins 11–18), whereas the 74ABT244 uses a single OE (pin 1) and interleaves inputs/outputs. Pin mapping differs fundamentally across all 20 positions.
