Diodes Incorporated PI5C3306LE

Overview

PI5C3306LE 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 A-to-B signal pass-through in notebook memory buses and low-power I/O expansion interfaces.

For engineers reviewing the PI5C3306LE datasheet, PI5C3306LE pinout, PI5C3306LE application, or PI5C3306LE equivalent, key selection criteria include on-resistance matching (5–15 Ω across V_CC/V_IN conditions), bus-enable timing (t_PZH/t_PLZ ≤ 4.9 ns), high-impedance isolation (±1 µA IOZ), and TSSOP-8 package compatibility with space-constrained PCB layouts.

Technical Context

The PI5C3306LE implements dual independent transmission-gate switches controlled by active-low enable inputs, supporting bidirectional signal routing without direction pins. Each switch exhibits matched R_ON (5 Ω typ. at V_CC = 4.5 V, V_IN = 0 V) and negligible added propagation delay-only RC-limited by load capacitance and switch resistance.

It operates across –40°C to +85°C ambient, supports 3.0 V to 5.0 V supply rails, and maintains logic-level compatibility with TTL and CMOS drivers via VIH ≥ 2.0 V and VIL ≤ 0.8 V. Input hysteresis (300 mV) ensures noise-immune enable control under noisy board conditions.

FAQ

What is the maximum capacitive load the PI5C3306LE can drive while maintaining <0.5 ns total propagation delay?

The PI5C3306LE's RC-limited delay is dominated by its 5 Ω R_ON and load capacitance. With a 50 pF load, the time constant is ~0.25 ns. To stay below 0.5 ns, the total load-including PCB trace, receiver input, and probe capacitance-must remain ≤100 pF, assuming nominal V_CC and 25°C ambient.

Does the PI5C3306LE support hot-swap or live-insertion without latch-up risk?

Yes-the PI5C3306LE features robust ESD protection (±2 kV HBM) and absolute maximum ratings that allow V_IN to swing from –0.5 V to +7.0 V independent of V_CC. Its CMOS transmission-gate structure prevents latch-up under hot-swap conditions when powered sequencing follows recommended guidelines in DS40491 Section 6.

Can BE1 and BE2 be tied together for synchronous switching of both channels?

Yes-BE1 and BE2 may be connected to a common control signal. The device's logic block diagram confirms independent gate control, and electrical characteristics (VIH/VIL, IIH/IIL) are specified per pin. No timing skew or interaction occurs between channels when enables are paralleled.

Is the PI5C3306LE qualified for automotive AEC-Q100 Grade 2 operation?

No-the PI5C3306LE is not AEC-Q100 qualified. Diodes Incorporated explicitly states in DS40491 that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing), and this part is intended for commercial/industrial applications with –40°C to +85°C ambient rating.
