Product details

Overview

PI5C16210AE from Pericom Semiconductor is a 20-bit, dual-port bus switch IC with 5 Ω ON-resistance, active-low bus enable (1OE/2OE), and flow-through pinout for low-noise, zero-propagation-delay signal routing in high-speed digital systems. It operates from 4 V to 5.5 V, supports –40°C to +85°C industrial temperature range, and delivers ultra-low quiescent power (0.5 μW typical).

For engineers reviewing the PI5C16210AE datasheet, PI5C16210AE pinout, PI5C16210AE application, or PI5C16210AE equivalent, key selection criteria include ON-resistance matching, bus enable timing (tPZH/tPLZ < 6.5 ns), flow-through layout compatibility, and Pb-free TSSOP-48 packaging compliance.

Technical Context

The PI5C16210AE implements two independent 10-bit bidirectional bus switches (Port 1: 1A/1B; Port 2: 2A/2B), each controlled by dedicated active-low enable inputs (1OE, 2OE). Its CMOS transmission-gate architecture ensures rail-to-rail analog/digital signal pass-through without level shifting.

Switching is governed by truth table logic: when xOE = L, Ax ↔ Bx conduct with R_ON = 5 Ω (typ); when xOE = H, both ports enter high-impedance state (I_OZH ≤ 10 μA). No internal latching or clocking circuitry is present - it is a purely static, voltage-controlled analog switch array.

Key Specifications

Parameter	Value and Actual Design Meaning
ON Resistance	5 Ω typical at VCC = 4.5 V, enabling direct bus coupling with minimal voltage drop and RC delay
Propagation Delay	0.25 ns (tPLH/tPHL) - contributes negligible delay beyond trace RC; system timing dominated by drivers/load
Quiescent Current	0.5 μW typical - allows integration into battery-sensitive notebook and portable designs without runtime penalty
Bus Enable Timing	tPZH = 1.5–6.3 ns, tPLZ = 1.5–5.5 ns - supports fast enable/disable sequencing in burst-mode data paths
Input Capacitance	2.4 pF (CIN) - minimizes loading on upstream drivers and preserves signal integrity at >100 MHz
Operating Voltage	4.0–5.5 V - compatible with 5 V TTL and mixed-voltage 4.5 V–5.5 V logic domains
Temperature Range	–40°C to +85°C - qualified for industrial-grade embedded control and communications equipment

Pinout & Package

PI5C16210AE is packaged in a 48-pin TSSOP (A48), 240-mil wide, lead-free and RoHS-compliant surface-mount package with 0.5 mm pitch and exposed thermal pad (per mechanical drawing A48).

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE	Active-Low Bus Enable Inputs	Enable/disable respective 10-bit port; asserted low enables bidirectional conduction between A/B buses
1A1–1A10, 2A1–2A10	Port A Input/Output Terminals	First and second 10-bit input/output bus segments; electrically identical to corresponding B pins when enabled
1B1–1B10, 2B1–2B10	Port B Input/Output Terminals	Complementary 10-bit bus terminals; mirror A-side signals with sub-ns delay when xOE active
GND (Pins 7, 22, 35)	Ground Reference	Three dedicated ground pins minimize ground bounce and ensure stable switching threshold reference
VCC (Pin 13)	Power Supply	Single 4–5.5 V supply powers all switches and control logic; no separate I/O or analog supply required

Key Features

Feature	Design Value
Near-zero propagation delay	0.25 ns typical - eliminates timing budget overhead in high-speed interconnects and memory expansion paths
Flow-through pinout (32×384 function)	Input and output pins aligned across package width - reduces layer count and vias in PCB routing
Ultra-low quiescent power	0.5 μW typical - enables always-on bus isolation in power-constrained portable and IoT edge nodes
5 Ω ON-resistance	Ensures <10 mV drop at 2 mA load - preserves logic margins and avoids signal degradation in 5 V systems
Industrial temperature support	–40°C to +85°C operation - validated for use in factory automation controllers and telecom line cards

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar 20-bit bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT16210DGGR	Higher R_ON (7 Ω typ), wider VCC range (4.5–5.5 V), no 4 V minimum support	Limited to 4.5 V+ systems; less suitable for 4.0 V brown-out tolerant designs	Prefer when higher drive strength needed and 4 V operation not required
74LVC162244APAG	Non-inverting buffer (not a switch), 3-state only, no bidirectional conduction, 24 mA drive	Requires direction control logic; adds propagation delay (~3.5 ns) and power consumption	Select only if unidirectional buffering with level translation is acceptable

Compared with SN74CBT16210DGGR and 74LVC162244APAG, PI5C16210AE uniquely combines 4 V operation, 5 Ω R_ON, and true bidirectional zero-delay switching - critical for low-voltage, high-fidelity bus sharing in portable and industrial systems.

FAQ

What is the maximum capacitive load the PI5C16210AE can drive while maintaining signal integrity?

The PI5C16210AE is characterized with CL = 50 pF for propagation delay measurements, and its 5 Ω R_ON forms an RC time constant of ~0.25 ns with that load. For reliable operation, total trace + load capacitance should remain ≤75 pF to avoid excessive rise-time degradation. Layout best practices (short traces, ground return paths) are recommended for >100 MHz signals.

Can PI5C16210AE be used with 3.3 V logic systems?

No - the PI5C16210AE requires VCC between 4.0 V and 5.5 V per datasheet specifications. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) are compatible with 3.3 V logic levels only when powered at ≥4.0 V, but it cannot operate from a 3.3 V supply. For 3.3 V systems, consider the PI3CH486 or SN74CBTLV3245.

Does PI5C16210AE support hot-swap or live-insertion?

Yes - its rail-to-rail analog switch architecture, absence of internal latches, and guaranteed high-impedance state (I_OZH ≤ 10 μA) during disable make it suitable for hot-swap applications. However, external current-limiting and ESD protection on A/B lines are recommended per system-level requirements.

Is the PI5C16210AE pin-compatible with other 48-pin bus switches like the SN74CBT16210?

No - although both are 20-bit bus switches in 48-pin packages, PI5C16210AE uses a flow-through pinout (A/B pairs aligned across package), whereas SN74CBT16210 uses interleaved A/B pin mapping. PCB layout and footprint are not interchangeable; redesign is required for substitution.
