Product details

Overview

74AHCT374PW,112 from NXP Semiconductors is an octal D-type transparent latch with 3-state outputs, designed for bus-oriented applications requiring data latching and isolation. It operates at 4.5–5.5 V supply, features 8 ns propagation delay at 5 V, supports 24 mA output drive, and is TTL-compatible with CMOS power efficiency.

For engineers reviewing the 74AHCT374PW,112 datasheet, 74AHCT374PW,112 pinout, 74AHCT374PW,112 application, or 74AHCT374PW,112 equivalent, key selection criteria include 3-state bus interface capability, propagation delay vs. supply voltage, output drive strength, and compatibility with legacy TTL logic families in mixed-signal control systems.

Technical Context

This device implements eight independent D-type latches with a common clock (CP) and output enable (OE) control. Each latch captures the D-input state on the rising edge of CP and holds it until the next clock edge, while OE independently gates all Q outputs to high-impedance.

The AHCT family combines TTL input thresholds (V_IL = 0.8 V max, V_IH = 2.0 V min) with CMOS output characteristics (rail-to-rail swing, low static current), enabling direct interfacing between 5 V TTL and CMOS systems without level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - Ensures robust operation across industrial-grade 5 V rails with ±10% tolerance.
Propagation Delay	8 ns @ V_CC = 5 V, T_A = 25 °C - Enables reliable timing in 100 MHz bus-latching applications.
Output Drive	±24 mA - Sufficient to drive 15 pF loads with <10 ns rise/fall times and fan-out of 10 LS-TTL loads.
Input Thresholds	V_IL ≤ 0.8 V, V_IH ≥ 2.0 V - Guarantees full compatibility with standard TTL logic levels.
Power Dissipation	2 μA typical I_CC @ V_CC = 5 V, no load - Delivers CMOS-level quiescent current in active bus-hold configurations.
Operating Temperature	−40 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments.

Pinout & Package

TSSOP-20 package: 20-pin thin shrink small outline package with 0.65 mm pitch, body width 4.4 mm, and exposed pad for thermal enhancement (not electrically connected).

Pin/Terminal	Circuit Role	Design Meaning
1–8 (D1–D8)	Data Inputs	Asynchronous inputs latched on rising CP edge; TTL-compatible thresholds ensure noise margin with legacy drivers.
9 (GND)	Ground Reference	Primary return path for logic and output current; requires low-inductance connection to minimize ground bounce.
10–17 (Q1–Q8)	3-State Outputs	Active-high latched outputs disabled to high-Z when OE = HIGH; supports bidirectional bus sharing.
18 (OE)	Output Enable	Active-low control (inverted logic); enables simultaneous tristate control of all eight outputs.
19 (CP)	Clock Input	Rising-edge-triggered latch control; Schmitt-trigger input not present-requires clean, monotonic clock edges.
20 (V_CC)	Supply Voltage	5 V nominal rail; decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable switching.

Key Features

Feature	Design Value
Octal latch with 3-state outputs	Enables single-chip replacement of eight discrete latches and buffers in data bus isolation paths.
TTL-compatible input thresholds	Eliminates need for external level translators when interfacing with 74LS/74F series controllers.
High-output drive (±24 mA)	Drives longer PCB traces and higher capacitive loads without signal integrity degradation.
Low quiescent current (2 μA)	Reduces system standby power in always-on industrial control modules with latched status registers.

Applications

Automotive Body Control Module

Use Scenario: Latching sensor status signals from analog-to-digital converters before multiplexed readout by microcontroller.

IC Role / Device Role / Timing Role: Data register holding sampled values during bus arbitration cycles; synchronized to system clock edge.

Use Value: Prevents metastability during concurrent sampling and readout, ensuring deterministic timing in cyclic executive firmware.

Use Scenario: Isolating door lock actuator command lines from shared CAN/LIN subsystem bus.

IC Role / Device Role / Timing Role: Output buffer/latch providing galvanic separation and drive strength for resistive solenoid loads.

Use Value: Enables safe hot-plug operation of peripheral modules without disrupting main bus communication timing.

Test Equipment Digital Pattern Generator

Legacy PC ISA Bus Interface Adapter

Use Scenario: Holding parallel stimulus patterns for FPGA-based digital test vectors applied to DUT pins.

IC Role / Device Role / Timing Role: Parallel data latch synchronizing pattern updates with test clock domain transitions.

Use Value: Achieves sub-10 ns setup/hold margin relative to FPGA I/O clock, critical for high-speed boundary scan.

Use Scenario: Interfacing modern microcontrollers to obsolete ISA bus peripherals via address/data latching.

IC Role / Device Role / Timing Role: Address latch capturing A0–A7 during ISA cycle initiation; data latch buffering D0–D7 during transfer.

Use Value: Maintains strict ISA timing compliance (t_ADL, t_DLH) without custom CPLD logic.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AHCT374PWR	Same logic function and pinout; identical AC/DC specs; differs only in packaging (TSSOP-20 vs. PW package code).	No functional difference; compatible in same PCB footprint but requires requalification for moisture sensitivity level (MSL) handling.	Select when sourcing from TI distribution channels or requiring TI-specific traceability documentation.
74HCT374PW,118	Same pinout and function; differs in V_CC range (4.5–5.5 V vs. 4.5–5.5 V) and propagation delay (10 ns vs. 8 ns at 5 V).	Suitable where 2 ns timing margin is non-critical; lower drive (±20 mA) limits trace length in high-speed layouts.	Prefer for cost-sensitive designs where 10 ns delay meets timing budget and reduced drive suffices.

Compared with SN74AHCT374PWR, the 74AHCT374PW,112 offers identical performance but different manufacturer qualification and MSL rating; versus 74HCT374PW,118, it delivers tighter timing and higher drive for demanding bus interfaces.

FAQ

What is the maximum clock frequency supported by the 74AHCT374PW,112?

The device does not specify a maximum clock frequency in its datasheet because it is an edge-triggered latch-not a synchronous register with internal feedback. Its usable frequency is determined by propagation delay (8 ns) and setup/hold time (3 ns/2 ns), supporting reliable operation up to approximately 80 MHz in well-designed PCB layouts with controlled impedance and proper termination.

Can the 74AHCT374PW,112 be used with 3.3 V logic systems?

No. The 74AHCT374PW,112 requires a 4.5–5.5 V supply and has TTL-compatible input thresholds (V_IH ≥ 2.0 V). While 3.3 V outputs may meet the minimum V_IH, they lack sufficient noise margin and violate recommended operating conditions. Use 74LVC374 or level-shifting buffers for 3.3 V system integration.

Is the output enable (OE) pin active-high or active-low?

The OE pin is active-low: when OE = LOW, the Q outputs reflect the latched D-input states; when OE = HIGH, all Q outputs enter high-impedance state. This matches industry-standard bus buffer convention and simplifies control logic using open-drain drivers or microcontroller GPIO with active-low enable mapping.

Does the 74AHCT374PW,112 include Schmitt-trigger inputs for noisy environments?

No. The 74AHCT374PW,112 uses standard CMOS input stages without hysteresis. Its input thresholds are fixed (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), making it unsuitable for directly interfacing with slow-rising or noisy signals. External RC filtering or dedicated Schmitt-trigger buffers (e.g., 74AHCT14) are required for such applications.
