Product details
Overview
74LVCH162373APAG from Renesas Electronics is a 3.3V CMOS 16-bit transparent D-type latch with 3-state outputs, 5V-tolerant I/O, bus-hold, and industrial temperature range (–40°C to +85°C). It functions as a bidirectional data latching and bus isolation device in mixed-voltage systems, featuring ±12mA drive strength, <500ps output skew, and 2.7V–3.6V VCC operation.
For engineers reviewing the 74LVCH162373APAG datasheet, 74LVCH162373APAG pinout, 74LVCH162373APAG application, or 74LVCH162373APAG equivalent, key selection criteria include 5V-tolerant I/O compatibility, dual 8-bit/latch-enable flexibility, bus-hold input retention, low-noise balanced drivers, and TSSOP-48 package suitability for high-density PCB layouts.
Technical Context
The 74LVCH162373APAG implements two independent 8-bit transparent latches controlled by separate Latch Enable (xLE) inputs and shared Output Enable (xOE) control per section. Its flow-through pinout and hysteresis-equipped inputs improve noise immunity in noisy industrial environments.
Each output features integrated series resistors to suppress switching noise under light loads, and all I/O pins support 5V signaling while powered from 3.3V - enabling seamless level translation without external components in 3.3V/5V mixed-supply systems.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16373APAG | No bus-hold; requires external pull resistors on unused inputs; identical TSSOP-48 footprint and 3.3V operation | Suitable only where input termination is externally managed; lacks floating-input protection | Select when bus-hold is unnecessary and cost minimization is prioritized |
| 74ALVCH162373TTR | Same bus-hold and 5V-tolerant I/O, but in TSSOP-48 tape-and-reel packaging; identical electrical specs | Identical functional behavior; differs only in packaging format and reel quantity | Select for automated SMT assembly requiring tape-and-reel delivery |

FAQ
What is the operating voltage range for the 74LVCH162373APAG?
The 74LVCH162373APAG operates over a VCC range of 2.7V to 3.6V, with nominal 3.3V ±0.3V performance specified. This extended range ensures robust functionality across varying power rail conditions in industrial systems, and all I/O pins remain fully 5V tolerant regardless of applied VCC within this window.
Does the 74LVCH162373APAG support true 5V-to-3.3V level translation?
Yes - the 74LVCH162373APAG supports bidirectional 5V-to-3.3V level translation without external components. Its inputs accept 0–5.5V signals while powered from 3.3V, and its outputs drive 5V-compatible logic levels, making it ideal for interfacing legacy 5V peripherals with modern 3.3V controllers in the 74LVCH162373APAG's target applications.
How does the bus-hold feature work in the 74LVCH162373APAG?
The 74LVCH162373APAG integrates bus-hold circuitry on all data input pins (1D1–1D8, 2D1–2D8), which actively retains the last valid logic state when inputs float. With ±75μA typical sustain current, it prevents undefined states and eliminates the need for external pull-up or pull-down resistors - a key reliability enhancement confirmed in the 74LVCH162373APAG's DC electrical characteristics table.
What is the maximum output skew specification for the 74LVCH162373APAG?
The 74LVCH162373APAG specifies a maximum output skew (tSK(o)) of 500ps across any two outputs switching in the same direction. This value is guaranteed over the full industrial temperature range (–40°C to +85°C) and ensures precise timing alignment critical for parallel bus capture applications using the 74LVCH162373APAG.
Can the 74LVCH162373APAG be used as two independent 8-bit latches?
Yes - the 74LVCH162373APAG is internally organized as two independent 8-bit sections, each with dedicated Latch Enable (1LE/2LE) and Output Enable (1OE/2OE) controls. This architecture allows simultaneous or staggered latching and 3-state control of two separate data streams, as explicitly defined in the 74LVCH162373APAG's function table and pin description.
