Product details

Overview

PI5C3306LEX from Diodes Incorporated is a 2-bit bus switch IC with two independent 5-Ω low-on-resistance CMOS switches, active-low enables (BE1/BE2), near-zero propagation delay (<0.25 ns), and ultra-low quiescent current (0.2 µA typical). It enables direct, bidirectional A↔B signal routing in notebook memory buses and low-power I/O expansion interfaces.

For engineers reviewing the PI5C3306LEX datasheet, PI5C3306LEX pinout, PI5C3306LEX application, or PI5C3306LEX equivalent, key selection criteria include on-resistance matching (5–15 Ω across V_CC and temperature), bus enable timing (t_PZL/t_PLZ ≤ 4.9 ns), high-impedance isolation (C_OFF = 5 pF), and TSSOP-8 package compatibility with space-constrained PCB layouts.

Technical Context

The PI5C3306LEX implements dual independent analog bus switches using NMOS-only transmission gates with no series PMOS, enabling true bidirectional signal flow without level-shifting or direction control logic. Each switch features matched R_ON (5 Ω typ. at V_CC = 4.5 V, I_ON = 30 mA) and negligible added propagation delay-only RC time constant (~0.25 ns for 50 pF load).

Its active-low enable architecture requires external pull-up resistors for power-up safety, and it operates across –40°C to +85°C ambient with supply voltage from –0.5 V to +7.0 V. Input hysteresis (300 mV) ensures noise-immune enable control under noisy system conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
R_ON	5 Ω typical at V_CC = 4.5 V - minimizes voltage drop and signal distortion in 3.3 V/5 V data paths
t_PLH/t_PHL	0.25 ns max - preserves signal integrity in high-speed parallel buses (e.g., PC133 SDRAM address/control)
I_CC	0.1–3.0 µA - enables always-on bus isolation in battery-powered notebooks without measurable drain
C_OFF	5 pF - ensures <1% capacitive loading when disabled, critical for maintaining signal rise/fall times
V_IL/V_IH	–0.5–0.8 V / 2.0 V - compatible with TTL and CMOS logic families without level translation
Operating Temp	–40°C to +85°C - supports industrial-grade notebook and embedded computing thermal profiles
Supply Range	–0.5 V to +7.0 V - accommodates transient overvoltage and mixed-voltage board designs

Pinout & Package

Package: 8-pin TSSOP (173-mil wide, Pb-free/Green compliant, JEDEC MO-153 variant).

Pin/Terminal	Circuit Role	Design Meaning
1 (BE1)	Enable input (active-low)	Asserts low to connect A1↔B1; requires external pull-up for defined state at power-up
2 (A1)	Bus A input/output	Bidirectional signal terminal; directly connected to B1 when BE1 = L
3 (B1)	Bus B input/output	Bidirectional signal terminal; electrically identical to A1 during conduction
4 (GND)	Ground reference	Common return path for all internal switches and logic; must be low-impedance
5 (A2)	Bus A input/output	Second independent bidirectional channel, isolated from A1/B1
6 (B2)	Bus B input/output	Second independent bidirectional channel, isolated from A1/B1
7 (BE2)	Enable input (active-low)	Asserts low to connect A2↔B2; independent timing control from BE1
8 (V_CC)	Power supply	Single-supply operation (3.0–5.5 V); powers both logic and analog switch sections

Key Features

Feature	Design Value
Ultra-low R_ON matching	5 Ω typical, ≤15 Ω over full V_CC/temp range - ensures consistent signal attenuation across channels and operating conditions
No added propagation delay	RC-limited only (≤0.25 ns for 50 pF) - eliminates timing budget overhead in synchronous bus designs
Active-low enable with hysteresis	300 mV input hysteresis - rejects noise on BE pins in electrically noisy laptop chassis environments
Zero static power in isolation	0.2 µA I_CC typical - enables permanent bus gating without compromising battery life in sleep states
High-impedance off-state	C_OFF = 5 pF, I_OZ = ±1 µA - prevents signal leakage between inactive subsystems (e.g., disabled peripherals)

Applications

Memory Bus Isolation

Low-Power I/O Expansion

Use Scenario: Isolating SDRAM address/control lines between CPU and memory controller during power-down sequences in ultraportable notebooks.

IC Role / Device Role / Timing Role: Bidirectional analog switch enabling/disabling signal paths without introducing skew or level shift.

Use Value: Eliminates cross-talk and standby current leakage while preserving nanosecond-level timing alignment across memory channels.

Use Scenario: Adding GPIO expansion capability to ARM-based embedded controllers via shared parallel bus with dynamic peripheral enable/disable.

IC Role / Device Role / Timing Role: Low-latency, low-R_ON bus gate for multiplexing sensor or display interface signals onto limited MCU pins.

Use Value: Enables hot-plug detection and power-gated peripheral management without signal degradation or added timing uncertainty.

PCI Express Sideband Routing

Legacy Interface Bridging

Use Scenario: Routing PCIe REFCLK or WAKE# sideband signals through shared board traces while maintaining signal integrity during link training.

IC Role / Device Role / Timing Role: Passive, bidirectional switch providing clean clock and control signal pass-through with minimal jitter addition.

Use Value: Reduces board layer count by sharing high-speed traces between multiple chipsets without requiring active repeaters or buffers.

Use Scenario: Interfacing legacy ISA or LPC bus peripherals to modern SoCs where native support is removed but electrical compatibility remains required.

IC Role / Device Role / Timing Role: Level-agnostic analog bridge that preserves TTL/CMOS voltage thresholds and timing margins.

Use Value: Extends product lifecycle of industrial control modules by enabling backward-compatible peripheral integration without FPGA glue logic.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-bit bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT3244DBR	Higher R_ON (7 Ω min), wider t_PLZ (6 ns), no input hysteresis	Less noise-immune in high-EMI laptop chassis; higher insertion loss in 5 V systems	Prefer when cost sensitivity outweighs timing/noise requirements
74LVC1G3157GW	Single-channel only, lower V_CC range (1.65–5.5 V), higher C_OFF (10 pF)	Requires two devices for 2-bit function; less effective isolation in high-frequency buses	Choose only for space-constrained single-line gating where dual-channel integration is unnecessary

Compared with SN74CBT3244DBR and 74LVC1G3157GW, the PI5C3306LEX delivers superior timing fidelity (0.25 ns vs. ≥6 ns disable delay), tighter R_ON matching, and built-in noise immunity-making it optimal for battery-sensitive, high-density notebook and embedded bus architectures.

FAQ

Does PI5C3306LEX support hot-swap or live-insertion?

No. The device lacks built-in hot-swap protection circuitry such as slew-rate control or current limiting. While its rail-to-rail input tolerance (–0.5 V to +7.0 V) allows safe operation during power sequencing, external current-limiting resistors and controlled ramp-up of V_CC are required before applying signals to A/B pins during live insertion.

Can PI5C3306LEX operate with 1.8 V logic levels?

Not reliably. Its guaranteed V_IH is 2.0 V minimum, and R_ON increases significantly below V_CC = 3.0 V. At 1.8 V supply, R_ON exceeds 22 Ω and input thresholds become undefined. Use only with 3.0 V, 3.3 V, or 5.0 V logic families per datasheet specifications.

What is the maximum capacitive load the PI5C3306LEX can drive?

The device itself does not specify a maximum load capacitance, but system-level propagation delay scales with R_ON × C_L. For ≤0.5 ns added delay, C_L should be ≤200 pF when R_ON = 5 Ω. Above 500 pF, signal rise/fall times degrade noticeably, and termination may be needed to prevent reflections in high-speed applications.

Is PI5C3306LEX qualified for automotive use?

No. The PI5C3306LEX is not AEC-Q100 qualified. Diodes Incorporated offers automotive-grade variants (e.g., PI5C3306Q) with PPAP documentation, extended temperature screening (–40°C to +125°C), and IATF 16949 manufacturing compliance-but this specific part number (LEX suffix) is commercial-grade only.
