Diodes Incorporated PI5A23157ZUAEX

Overview

PI5A23157ZUAEX from Diodes Incorporated is a low-voltage dual SPDT analog switch fabricated in CMOS technology, designed for signal routing in bus and analog applications. It operates across 1.65 V to 5.5 V supply, delivers 220 MHz signal bandwidth, features rail-to-rail signal handling, and supports break-before-make switching for glitch-free audio/video and communication circuits.

For engineers reviewing the PI5A23157ZUAEX datasheet, PI5A23157ZUAEX pinout, PI5A23157ZUAEX application, or PI5A23157ZUAEX equivalent, key selection criteria include on-resistance (10 Ω typ. at 5 V), off-isolation (–65 dB @ 10 MHz), crosstalk rejection (–66 dB @ 10 MHz), 10-pin UQFN package (2 mm × 1.5 mm), and extended industrial temperature range (–40°C to +125°C).

Technical Context

The PI5A23157 implements two independent SPDT analog switches with complementary NC/NO/COM terminal configurations per channel, controlled by dedicated IN1 and IN2 digital inputs. Each switch enforces break-before-make timing (≤0.5 ns) to prevent momentary shorting during state transitions.

Its CMOS architecture enables rail-to-rail analog signal handling (0 V to V+), low charge injection (7 pC typ.), and high dynamic performance: 220 MHz 3dB bandwidth, <12 ns turn-on time (5 V), and <8 ns turn-off time (5 V), all while maintaining sub-1 μA quiescent current.

Key Specifications

FAQ

What is the maximum signal frequency supported by PI5A23157ZUAEX?

The PI5A23157ZUAEX supports a 3dB bandwidth of 220 MHz at +25°C with 50 Ω load, verified per Test Circuit Figure 6 in DS43541 Rev 3-2. This enables reliable routing of HD video clock signals, USB 2.0 data, and wideband sensor outputs without significant amplitude roll-off.

Does PI5A23157ZUAEX support 1.8 V logic control with 5 V analog signals?

Yes. With V+ = 5 V, the device accepts 1.8 V logic-high inputs (VIH ≥ 0.75×V+ = 3.75 V minimum at 5 V, but functional down to ~1.3 V due to CMOS threshold margin). However, for guaranteed 1.8 V logic compatibility, V+ must be ≤ 2.4 V (since VIH min = 0.75×V+). At 5 V supply, use 3.3 V or 5 V logic levels.

Can PI5A23157ZUAEX be used in automotive applications?

The PI5A23157ZUAEX is not AEC-Q100 qualified. While it operates across –40°C to +125°C and meets industrial reliability standards, Diodes explicitly states that automotive-grade variants require PPAP capability and IATF 16949 manufacturing - contact Diodes directly for qualified alternatives like the AP21xx series or automotive-specific analog switches.

How does break-before-make timing prevent signal disruption?

Break-before-make ensures the NC path opens fully before the NO path closes (tBBM ≤ 0.5 ns), eliminating any momentary short between NC and NO terminals. This avoids transient shorts in audio paths (preventing pops), prevents bus contention in shared analog buses, and maintains signal integrity during hot-swap or dynamic reconfiguration.
