Product details

Overview

PI74ALVCH162244VE from Pericom Semiconductor is a 16-bit non-inverting 3-state buffer/driver for low-voltage bus interface applications, operating at V_CC = 2.3V–3.6V, featuring Bus Hold inputs, 26-Ω integrated series output resistors, and symmetrical active-low OE controls. It supports flexible partitioning as four 4-bit, two 8-bit, or one 16-bit buffer in memory address, clock, and data bus systems.

For engineers reviewing the PI74ALVCH162244VE datasheet, PI74ALVCH162244VE pinout, PI74ALVCH162244VE application, or PI74ALVCH162244VE equivalent, key selection criteria include 3-state drive capability, input hysteresis, output ground bounce (VOLP < 0.8V), VOH undershoot (VOHV < 2.0V), and industrial temperature range (–40°C to +85°C).

Technical Context

This device implements a CMOS-based 16-bit non-inverting buffer with four independent 4-bit sections, each controlled by its own active-low output-enable (OE) input. Each section provides high-impedance (Z) outputs when OE is HIGH, and drives logic levels with matched rise/fall times under load.

Bus Hold circuitry actively retains the last valid logic state on each input during high-impedance conditions, eliminating external pullup/down resistors. Input hysteresis improves noise immunity, while integrated 26-Ω series output resistors suppress ringing without requiring external termination.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.3V to 3.6V - Enables interoperability with 2.5V and 3.3V logic families without level-shifting.
Propagation Delay	Typ. 3.6ns at V_CC = 3.3V - Supports high-speed bus operation up to ~100 MHz system timing.
Output Drive	±24mA at V_CC = 3.3V - Sufficient to drive 50pF loads across PCB traces or multiple CMOS inputs.
VOLP / VOHV	<0.8V / <2.0V at V_CC = 3.3V - Minimizes switching noise and ground bounce in dense digital layouts.
Input Hysteresis	Present on all inputs - Increases noise margin by ~300mV, critical for noisy industrial environments.
Bus Hold Current	±45µA at V_CC = 3.3V - Maintains stable input state during hot-swap or unconnected bus segments.
Operating Temp	–40°C to +85°C - Qualified for industrial-grade embedded control and communications equipment.

Pinout & Package

Package: 48-pin plastic SSOP (300 mil wide), JEDEC MO-153 compliant, body width 12.0mm, lead pitch 0.635mm.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE, 3OE, 4OE	Active-low output enable	Independent control per 4-bit group; must be pulled HIGH via resistor during power-up to ensure Z-state.
1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3	Data inputs	16 total inputs with Bus Hold and hysteresis; tolerate floating states without external biasing.
1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3	Non-inverting buffered outputs	16 outputs with integrated 26-Ω series resistance; reduce EMI and eliminate external damping resistors.
V_CC (Pins 9, 10, 41, 42)	Power supply	Four dedicated V_CC pins minimize IR drop and improve simultaneous switching noise immunity.
GND (Pins 4–7, 33–36)	Ground reference	Eight GND pins provide low-inductance return paths for all output groups and reduce ground bounce.

Key Features

Feature	Design Value
Bus Hold inputs	Maintains last valid logic state on disconnected inputs, removing need for 10kΩ pullup/down resistors per line.
Integrated 26-Ω output resistors	Eliminates external series termination components and simplifies layout for point-to-point or stubbed bus topologies.
Symmetrical active-low OE	Enables independent gating of four 4-bit channels, supporting partial bus isolation in multi-master systems.
Hysteresis on all inputs	Provides ~300mV noise margin, improving reliability in electrically noisy industrial or motor-control environments.
Low ground bounce (VOLP < 0.8V)	Reduces risk of false triggering in adjacent logic due to simultaneous output switching transients.

Applications

Memory Address Buffering

Clock Distribution

Use Scenario: Driving address lines from a microcontroller to multiple SRAM or Flash devices sharing a common data bus.

IC Role / Device Role / Timing Role: Non-inverting 16-bit buffer with 3-state control isolates address latching and prevents bus contention during read/write cycles.

Use Value: Integrated Bus Hold maintains stable address state during chip select transitions, reducing setup/hold timing uncertainty.

Use Scenario: Distributing a single system clock to multiple synchronous peripherals (e.g., ADCs, DACs, FPGAs) with matched trace lengths.

IC Role / Device Role / Timing Role: Low-skew, non-inverting fanout buffer with controlled edge rates minimizes clock skew and jitter accumulation.

Use Value: 26-Ω series resistors dampen reflections on unterminated clock traces, preserving signal integrity without added BOM cost.

Industrial I/O Expansion

Hot-Swappable Backplane Interface

Use Scenario: Interfacing a PLC CPU module to remote I/O racks over extended backplane traces subject to EMI and voltage droop.

IC Role / Device Role / Timing Role: Voltage-tolerant 2.3V–3.6V buffer with hysteresis ensures reliable level translation and noise rejection in factory-floor environments.

Use Value: –40°C to +85°C rating and robust input thresholds support uninterrupted operation in unconditioned control cabinets.

Use Scenario: Enabling safe insertion/removal of daughter cards in a modular telecom or test equipment backplane.

IC Role / Device Role / Timing Role: 3-state outputs isolate card-specific address/data buses during hot-plug events; OE pins sequenced with power rails.

Use Value: Bus Hold preserves last known bus state during power ramp-up/down, preventing spurious writes or resets during card insertion.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit non-inverting 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALVCH162244DGGR	TI part; identical pinout, same V_CC range, but no Bus Hold; requires external pullups.	Lacks input state retention - unsuitable where inputs may float during power sequencing or hot-swap.	Select if external biasing is already present and cost sensitivity outweighs design simplicity.
74LVC162244APAG	IDT part; 48-pin TSSOP, V_CC = 1.65V–3.6V, includes Bus Hold, but propagation delay ~5.2ns (slower).	Broadened voltage range enables 1.8V compatibility, but reduced speed limits use in >80MHz clock domains.	Select for mixed-voltage systems needing 1.8V support, accepting minor timing penalty.

Compared with SN74ALVCH162244DGGR and 74LVC162244APAG, PI74ALVCH162244VE uniquely combines Bus Hold, 3.6ns speed, and 26-Ω outputs in a single industrial-grade package-ideal where board space, noise immunity, and plug-and-play reliability are prioritized.

FAQ

What is the recommended pull-up resistor value for OE pins during power-up?

A minimum 10kΩ pull-up resistor to V_CC is recommended for each OE pin to guarantee high-impedance output state at power-on. This value balances current consumption (<0.3mA per OE at 3.3V) and noise immunity, and aligns with the device's specified I_OH sink capability of 40µA.

Does PI74ALVCH162244VE require external termination resistors on its outputs?

No. Each output includes an integrated 26-Ω series resistor optimized for driving typical PCB traces and capacitive loads up to 50pF. External termination is unnecessary unless driving long (>15cm) or heavily loaded transmission lines where impedance matching becomes critical.

Can PI74ALVCH162244VE operate reliably at 2.5V V_CC?

Yes. The device is fully specified from 2.3V to 3.6V, including propagation delay, drive strength, and noise margins. At 2.5V, t_PD increases to ~4.8ns and output drive reduces to ±18mA, remaining sufficient for most 2.5V LVTTL and LVCMOS interfaces.

How does Bus Hold function interact with unused inputs during PCB layout?

Bus Hold actively maintains the last driven logic state on any input left unconnected, eliminating floating nodes. No routing or pull resistors are needed-even for unused A/Y pairs-reducing layout complexity and preventing metastability in downstream logic triggered by indeterminate inputs.
