Nexperia USA Inc. 74LVC16245ADL,112

Overview

74LVC16245ADL,112 from Nexperia is a 16-bit 3-state bus transceiver with dual direction control (1DIR/2DIR) and dual output enables (1OE/2OE), operating from 1.2 V to 3.6 V supply. It supports bidirectional data flow between two 8-bit buses or one 16-bit bus, features 5 V-tolerant inputs, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It is used in mixed-voltage board-level interconnects such as FPGA-to-ASIC data paths in industrial control backplanes.

For engineers reviewing the 74LVC16245ADL,112 datasheet, 74LVC16245ADL,112 pinout, 74LVC16245ADL,112 application, or 74LVC16245ADL,112 equivalent, this device serves as a voltage-level translating transceiver in high-density PCB designs requiring low-noise, low-power, and robust bus hold (in LVCH variant) - though 74LVC16245ADL,112 itself lacks bus hold per datasheet Rev. 16.

Technical Context

This transceiver implements two independent 8-bit bidirectional channels, each with dedicated DIR and OE pins enabling granular control over data flow direction and output state. Its CMOS architecture ensures low static current (≤80 μA at VCC = 3.6 V) and supports dynamic operation up to 200 MHz effective throughput via sub-6 ns propagation delay (VCC = 3.3 V).

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while Schmitt-trigger inputs tolerate slow-rising signals and reject noise below 0.35VCC–0.8 V thresholds. Input voltage range spans –0.5 V to +5.5 V, enabling safe interfacing with 5 V TTL logic despite a 3.6 V max VCC.

FAQ

Does 74LVC16245ADL,112 support bus hold functionality?

No. Bus hold is exclusive to the 74LVCH16245A variant (e.g., 74LVCH16245ADL,112). The 74LVC16245A version lacks internal bus hold circuitry on data inputs, requiring external pull-up/pull-down resistors for unused pins to prevent floating states and potential shoot-through current.

What is the maximum clock frequency supported for synchronous data transfer?

The device does not include an internal clock; it is asynchronous. However, its 4.5 ns max propagation delay (VCC = 3.3 V) supports reliable data handshaking up to ~100 MHz in well-terminated 16-bit parallel buses, assuming ≤15 pF load and controlled trace impedance.

Can 74LVC16245ADL,112 be operated at 1.2 V supply while interfacing with 5 V inputs?

Yes. The datasheet explicitly specifies 5 V tolerance on all inputs at VCC = 1.2 V to 3.6 V. Input clamp diodes and robust oxide design allow VI up to +5.5 V regardless of VCC, enabling safe level translation without external protection components.

Is the TSSOP48 package (SOT362-1) RoHS compliant and lead-free?

Yes. Per Nexperia's product change notification and packaging documentation, the 74LVC16245ADL,112 in SOT362-1 (TSSOP48) is fully RoHS compliant, halogen-free, and uses lead-free matte tin terminations meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements.
