Renesas IDT74LVC16823APAG8

Overview

IDT74LVC16823APAG8 from Integrated Device Technology is a 3.3V CMOS 18-bit register with 3-state outputs and 5V-tolerant I/O, designed for data synchronization and buffering in mixed-voltage systems. It supports dual 9-bit or single 18-bit operation via independent clock enable and asynchronous clear controls, features ±24mA output drive, <500ps output skew, and operates across –40°C to +85°C.

For engineers reviewing the IDT74LVC16823APAG8 datasheet, IDT74LVC16823APAG8 pinout, IDT74LVC16823APAG8 application, or IDT74LVC16823APAG8 equivalent, key selection criteria include 5V-tolerant I/O compatibility, industrial temperature range support, tPLH/tPHL ≤ 8ns at 3.3V, 3-state output control timing, and SSOP-56 package layout constraints.

Technical Context

The IDT74LVC16823APAG8 implements two independent 9-bit register banks sharing VCC/GND but with separate clock (xCLK), clock enable (xCLKEN), clear (xCLR), and output enable (xOE) controls per bank - enabling flexible partitioned or unified 18-bit storage. Each bank drives nine 3-state outputs with hysteresis-equipped inputs for noise immunity.

Its dual-metal CMOS process delivers CMOS power levels (0.4μW static), 5V-tolerant I/O pins (–0.5V to +6.5V terminal voltage), and hot-insertion capability. Output drivers are rated for ±24mA sink/source under load while maintaining sub-8ns propagation delay and <500ps inter-output skew within the same package.

FAQ

What is the maximum clock frequency supported by the IDT74LVC16823APAG8?

The IDT74LVC16823APAG8 supports a maximum clock frequency of 150 MHz across its full operating range (–40°C to +85°C) at VCC = 2.7V or 3.3V. This is specified under switching characteristics with tW (clock pulse width) ≥ 3.3 ns, ensuring reliable setup and hold timing margins for synchronous data capture in high-speed digital systems.

Does the IDT74LVC16823APAG8 require external pull-up or pull-down resistors on control inputs?

No, the IDT74LVC16823APAG8 does not require external pull-up or pull-down resistors on control inputs such as 1OE, 2OE, 1CLKEN, or 1CLR because all inputs feature built-in hysteresis (100 mV typical at VCC = 3.3V), which provides sufficient noise immunity and stable logic thresholds even with slow-rising or floating signals in industrial environments.

Can the IDT74LVC16823APAG8 be used to translate between 5V and 3.3V logic levels bidirectionally?

The IDT74LVC16823APAG8 supports unidirectional voltage translation: its inputs accept 0V–5.5V signals (5V-tolerant), and its outputs swing rail-to-rail between GND and VCC (3.3V). It cannot drive 5V logic directly from its outputs, so true bidirectional level translation requires external circuitry - but it functions reliably as a 5V-to-3.3V input translator and 3.3V bus driver.

What is the meaning of "flow-through pin organization" for the IDT74LVC16823APAG8?

"Flow-through pin organization" means data input pins (e.g., 1D1–1D9) and corresponding output pins (1Q1–1Q9) are arranged on opposite sides of the TSSOP-56 package in aligned positions - enabling straight, short PCB traces with minimal layer changes. This reduces parasitic inductance/capacitance, lowers crosstalk, and simplifies layout for high-speed parallel interfaces.

Is the IDT74LVC16823APAG8 pin-compatible with earlier IDT74LVC16823A variants in TSSOP-56?

Yes, the IDT74LVC16823APAG8 is pin-compatible with all IDT74LVC16823A variants packaged in TSSOP-56 (e.g., IDT74LVC16823APAG), as confirmed by IDT's ordering information and pin configuration diagrams. The '8' suffix denotes tape-and-reel packaging; electrical, thermal, and mechanical specifications remain identical across PAG and PAG8 variants.
