Product details

Overview

74LVT16374ADGG,112 from NXP Semiconductors is a 16-bit transparent D-type latch with 3-state outputs, designed for high-speed bus interface applications in industrial control and telecom backplanes. It operates at 3.3 V supply, supports 160 MHz maximum clock frequency, features ±24 mA output drive, and has 2.8 ns propagation delay (t_PD) at V_CC = 3.3 V.

For engineers reviewing the 74LVT16374ADGG,112 datasheet, 74LVT16374ADGG,112 pinout, 74LVT16374ADGG,112 application, or 74LVT16374ADGG,112 equivalent, key selection criteria include 3.3 V LVT logic compatibility, simultaneous 16-bit latching capability, bus-hold functionality absence, and TSSOP48 thermal performance under sustained 160 MHz toggle conditions.

Technical Context

This device implements dual 8-bit transparent latches in a single TSSOP48 package, with separate clock (CLK) and output-enable (OE) controls per 8-bit section. Each latch stage uses true D-type flip-flop architecture with non-inverted data path and edge-triggered clock input.

It conforms to IEEE 1194.1 LVT logic family specifications, ensuring interoperability with other 3.3 V LVT devices. Input thresholds are TTL-compatible (V_IH = 2.0 V min, V_IL = 0.8 V max), while outputs meet 3.3 V CMOS voltage levels with rail-to-rail swing.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	LVT (Low-Voltage TTL) - enables mixed-voltage interfacing between 3.3 V and 5 V systems without level shifters
Supply Voltage	3.0 V to 3.6 V - ensures stable operation across industrial temperature range with minimal supply regulation
Max Clock Frequency	160 MHz - supports high-throughput data capture in synchronous bus architectures
Propagation Delay	2.8 ns (t_PD) - guarantees sub-3 ns timing margin for 300 Mbps parallel bus designs
Output Drive	±24 mA - drives 50 Ω transmission lines directly without external buffers
Operating Temperature	–40 °C to +85 °C - qualified for extended industrial environments including base station control cards

Pinout & Package

TSSOP48 (Thin Shrink Small Outline Package, 48-pin, 0.4 mm pitch, 12.5 mm × 6.1 mm body size, 1.2 mm max height). Thermal pad on underside requires solder connection for optimal junction-to-board thermal resistance (R_θJB = 32 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17	Data Inputs (D0–D15)	Asynchronous parallel data inputs accepting TTL/CMOS logic levels; no internal pull-ups or bus-hold
9, 25	Clock Inputs (CLKA, CLKB)	Positive-edge-triggered clocks controlling latch enable per 8-bit bank; asynchronous to each other
18, 19, 20, 21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34	Outputs (Q0–Q15)	3-state outputs with independent OE control; high-impedance state active when OE = HIGH
25, 35	Output Enables (OEA, OEB)	Active-HIGH enables for respective 8-bit output banks; no internal debouncing or glitch filtering
48, 24	V_CC, GND	Dual power/ground pairs reduce simultaneous switching noise; decoupling required within 5 mm of each pair

Key Features

Feature	Design Value
16-bit transparent latching	Enables full-word data capture on rising clock edge without pipeline latency or setup/hold dependency on downstream logic
3.3 V LVT logic compatibility	Guarantees interoperability with legacy 5 V TTL systems via input threshold design, eliminating need for external level translators
±24 mA output drive strength	Supports direct termination into 50 Ω PCB traces, reducing component count and signal integrity risk in high-speed backplane interfaces
2.8 ns propagation delay	Meets timing closure for 300 Mbps parallel data buses operating at 150 MHz system clock with 1 ns skew budget

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit transparent latch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC16374ADGGR	LVC family (3.3 V CMOS); lower drive (±24 mA same), but higher t_PD (3.7 ns) and no LVT input threshold compatibility	Requires level translation when interfacing with 5 V TTL sources; unsuitable for mixed-voltage backplanes	Select only if system uses pure 3.3 V CMOS signaling and timing budget allows +0.9 ns delay penalty
74ALVCH16374PAG8	ALVCH family (2.5/3.3 V); supports 2.5 V operation, but reduced drive (±12 mA) and higher t_PD (4.2 ns)	Not rated for 3.3 V-only industrial temp range; limited to commercial grade (0 °C to +70 °C)	Use only in cost-sensitive consumer applications where 2.5 V support is mandatory and thermal margin is not constrained

Compared with SN74LVC16374ADGGR and 74ALVCH16374PAG8, the 74LVT16374ADGG,112 uniquely delivers 160 MHz operation with 5 V-tolerant inputs and industrial-grade thermal performance-making it the sole option for legacy-compatible, high-speed bus isolation in telecom and industrial control.

FAQ

Is the 74LVT16374ADGG,112 compatible with 5 V TTL input signals?

Yes. Its input thresholds meet TTL specifications (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), allowing direct connection to 5 V TTL outputs without level shifting. This is a defining feature of the LVT family and is verified in NXP's datasheet revision 9.1, Section 7.2.

Does this device include bus-hold or weak pull-up circuitry on inputs?

No. The 74LVT16374ADGG,112 has no internal bus-hold or pull-up resistors. All inputs are high-impedance CMOS/TTL-compatible nodes requiring externally defined logic states when unused or floating, per NXP Application Note AN10412.

What is the recommended decoupling strategy for TSSOP48 layout?

Place one 100 nF X7R ceramic capacitor within 3 mm of each V_CC/GND pair (pins 48 & 24), plus a shared 4.7 µF tantalum near the package center. Avoid daisy-chained power routing; use dedicated planes with minimum 0.3 mm trace width for GND returns.

Can both 8-bit sections operate independently with different clocks and enables?

Yes. CLKA (pin 9) and CLKB (pin 25) are fully independent clock inputs, and OEA (pin 25) and OEB (pin 35) provide separate 3-state control. This allows concurrent latching and output gating of two 8-bit data streams without cross-talk or timing dependency.
