Texas Instruments CLVC16244AIDGGREP

Overview

CLVC16244AIDGGREP from Texas Instruments is a 16-bit noninverting buffer/driver with 3-state outputs, designed for 1.65-V to 3.6-V V_CC operation. It features four independent 4-bit sections, each with active-low output-enable (OE) control, true logic outputs, and I_off support for partial-power-down mode. It enables mixed-voltage interfacing (5-V inputs with 3.3-V V_CC) and is used in memory address buffering, clock distribution, and bus-transceiver applications.

For engineers reviewing the CLVC16244AIDGGREP datasheet, CLVC16244AIDGGREP pinout, CLVC16244AIDGGREP application, or CLVC16244AIDGGREP equivalent, key selection criteria include its 4.1-ns max propagation delay at 3.3 V, ±24-mA output drive capability, 3.3-V/5-V mixed-mode signal compatibility, I_off protection, and TSSOP-48 package suitability for high-density PCB layouts.

Technical Context

This device implements four independent 4-bit noninverting buffers, each with dedicated active-low OE control (1OE–4OE), enabling flexible partitioning as one 16-bit, two 8-bit, or four 4-bit drivers. All inputs tolerate up to 5.5 V regardless of V_CC, supporting level translation in heterogeneous voltage systems.

It employs standard CMOS logic with I_off circuitry that disables outputs during power-down to prevent backflow current, and meets JESD 17 latch-up performance (>250 mA) and JESD 22 ESD ratings (2000-V HBM, 1000-V CDM). Output switching is characterized across 1.65–3.6 V with guaranteed t_pd, t_en, and t_dis parameters.

FAQ

What is the maximum operating frequency supported by CLVC16244AIDGGREP?

The CLVC16244AIDGGREP does not specify a maximum clock frequency in its datasheet because it is a non-clocked buffer - its speed is defined by propagation delay (t_pd ≤4.1 ns at 3.3 V) and transition rate (∆t/∆v ≤10 ns/V). It reliably handles data rates up to ~200 MHz in well-terminated, low-capacitance bus environments, limited by board layout and load, not internal architecture. CLVC16244AIDGGREP is commonly used for address, control, and clock distribution-not data streaming-so bandwidth is governed by edge rate, not periodicity.

Does CLVC16244AIDGGREP support hot-swap or live-insertion applications?

Yes, CLVC16244AIDGGREP supports partial-power-down operation via its I_off feature: when V_CC = 0 V, input and output leakage remains ≤±10 µA, preventing damaging back-current flow from live buses into the unpowered device. This makes CLVC16244AIDGGREP suitable for hot-swap backplanes and modular systems, provided OE is held inactive (high) during insertion to avoid bus contention. CLVC16244AIDGGREP's 5.5-V input tolerance further enhances robustness during transitional states.

Can CLVC16244AIDGGREP be used as a level shifter between 5-V and 3.3-V logic domains?

Yes, CLVC16244AIDGGREP functions as a unidirectional level shifter: its inputs accept 0–5.5 V regardless of V_CC, while outputs swing rail-to-rail between GND and the applied V_CC (1.65–3.6 V). When powered at 3.3 V, it safely translates 5-V inputs to 3.3-V outputs without external components. CLVC16244AIDGGREP does not support bidirectional translation or 3.3-V-to-5-V upshifting, as outputs cannot exceed V_CC.

What is the recommended pull-up resistor value for OE pins on CLVC16244AIDGGREP?

Texas Instruments recommends tying OE pins to V_CC through a pullup resistor to ensure high-impedance state during power-up/power-down transients. The minimum resistance is determined by the current-sinking capability of the driving source - typically ≥10 kΩ for standard logic drivers. For robust noise immunity in industrial environments, 4.7-kΩ to 10-kΩ is common. CLVC16244AIDGGREP's OE inputs draw ≤5 µA (I_I), so even 100-kΩ provides adequate bias; lower values improve transient response but increase static current. CLVC16244AIDGGREP's datasheet specifies no absolute minimum, but 10-kΩ is widely validated in reference designs.

Is CLVC16244AIDGGREP pin-compatible with other members of the LVC16244 family?

Yes, CLVC16244AIDGGREP is pin-compatible with all SN74LVC16244A variants in TSSOP-48 (DGG) packaging, including SN74LVC16244ADGGR and SN74LVC16244A-Q1. The pinout, electrical characteristics, and functional behavior are identical across these parts; differences lie solely in qualification level (EP vs. commercial vs. automotive), temperature range, and manufacturing pedigree. CLVC16244AIDGGREP can be substituted on existing DGG-layout PCBs without modification, provided the application requirements align with its enhanced-product specifications.
