Texas Instruments 74LVTH162374GRDR

Overview

74LVTH162374GRDR from Texas Instruments is a 3.3-V ABT 16-bit edge-triggered D-type flip-flop with 3-state outputs in a 54-ball VFBGA (GRD) package. It features dual 8-bit banks, 22-Ω integrated series output resistors, bus-hold on all data inputs, and Ioff support for hot insertion. It operates from 2.7 V to 3.6 V and is used in high-speed bidirectional bus interfaces and I/O port buffering.

For engineers reviewing the 74LVTH162374GRDR datasheet, 74LVTH162374GRDR pinout, 74LVTH162374GRDR application, or 74LVTH162374GRDR equivalent, key selection criteria include its 160 MHz maximum clock frequency, 2.8 ns data setup time at 3.3 V, 12 mA output drive capability, mixed-mode 5-V-tolerant inputs, and GRD package thermal resistance of 36 °C/W.

Technical Context

The 74LVTH162374GRDR implements two independent 8-bit positive-edge-triggered D-type flip-flop banks, each with dedicated clock (1CLK/2CLK) and output-enable (1OE/2OE) controls. Its ABT (Advanced BiCMOS Technology) architecture enables TTL-level compatibility while operating at 3.3 V VCC.

It integrates bus-hold circuitry on all 16 data inputs to maintain valid logic states without external pullups, and features power-up/power-down 3-state and Ioff protection to prevent backdrive current during hot insertion. Output pins include built-in 22-Ω series resistors to suppress switching noise.

FAQ

What is the maximum operating frequency of the 74LVTH162374GRDR?

The 74LVTH162374GRDR supports a maximum clock frequency of 160 MHz under recommended operating conditions (VCC = 3.3 V ±0.3 V, TA = –40°C to 85°C). This value is confirmed in the Switching Characteristics table of the official TI datasheet SCBS262M, and applies to both banks independently when loaded with CL = 50 pF.

Does the 74LVTH162374GRDR support hot insertion?

Yes, the 74LVTH162374GRDR supports hot insertion via dual protection mechanisms: Ioff circuitry disables outputs when VCC = 0 V to prevent backdrive current, and power-up 3-state holds outputs in high-impedance during power ramp-up. These features are explicitly validated in TI's production testing per the datasheet's "Ioff and Power-Up 3-State Support Hot Insertion" feature bullet.

What package type is used for the 74LVTH162374GRDR?

The 74LVTH162374GRDR uses a 54-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA) package designated GRD (or ZRD for Pb-free). Its mechanical dimensions are 7.0 mm × 4.5 mm × 1.0 mm with 0.5-mm ball pitch, and it follows JEDEC MO-164AA standards as documented in TI's packaging addendum.

Can the 74LVTH162374GRDR interface with 5-V logic inputs while operating at 3.3 V?

Yes, the 74LVTH162374GRDR accepts input voltages up to 5.5 V on all data and control pins while powered at VCC = 3.3 V. This mixed-mode operation is guaranteed per the "Recommended Operating Conditions" table (VI = 5.5 V max) and enables direct connection to 5-V TTL outputs without external level-shifting circuitry.

How does bus-hold functionality work on the 74LVTH162374GRDR?

The 74LVTH162374GRDR integrates active bus-hold circuitry on all 16 data inputs, which maintains the last-valid logic state when inputs float. It sources or sinks up to ±750 µA (at VCC = 3.6 V) to hold the line - eliminating the need for external pullup/pulldown resistors and reducing system-level component count and board area.
