Nexperia USA Inc. 74LVC16245ADL,118

Overview

74LVC16245ADL,118 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 while tolerating 5.5 V inputs. It supports bidirectional data flow between two 8-bit buses or one 16-bit bus, features Schmitt-trigger inputs for noise immunity, and includes IOFF partial power-down protection. It is used in mixed-voltage board-level interconnects such as FPGA-to-ASIC data routing in industrial control backplanes.

For engineers reviewing the 74LVC16245ADL,118 datasheet, 74LVC16245ADL,118 pinout, 74LVC16245ADL,118 application, or 74LVC16245ADL,118 equivalent, this device serves as a voltage-tolerant, low-power bidirectional interface for 3.3 V logic domains interfacing with 5 V legacy peripherals, requiring precise timing control, bus hold capability (in LVCH variant), and robust ESD resilience per JS-001 Class 2.

Technical Context

This transceiver implements dual independent 8-bit channels, each with dedicated DIR and OE pins enabling granular control of direction and output state. Its CMOS architecture delivers rail-to-rail switching with propagation delays as low as 1.0 ns at 3.3 V, and its IOFF circuit actively disables outputs during power-down to prevent backflow current.

Schmitt-trigger inputs ensure reliable operation with slow-rising signals, while the 5.5 V tolerant input structure allows direct connection to 5 V TTL outputs without level-shifting. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2 V–3.6 V VCC range.

FAQ

Is 74LVC16245ADL,118 pin-compatible with 74LVCH16245ADL,118?

Yes-both share identical TSSOP48 (SOT362-1) pinout, supply voltage range, timing specs, and functional behavior. The only difference is that the LVCH variant integrates bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed for substitution.

Can 74LVC16245ADL,118 operate reliably at 1.2 V supply?

Yes-it is fully specified down to 1.2 V, with propagation delay ≤13.0 ns and output drive capability maintained per datasheet Table 6. At 1.2 V, VIH is 1.08 V and VOL remains ≤0.12 V at 100 μA load, enabling use in ultra-low-power battery-operated systems.

What is the maximum data rate supported by this transceiver?

While not a serial device, its 1.0 ns typical propagation delay at 3.3 V supports parallel bus clocking up to ~200 MHz (5 ns round-trip timing margin). Real-world throughput depends on bus loading and PCB trace length; for 30 pF load and 5 cm traces, reliable operation exceeds 100 MHz data strobe rates.

Does 74LVC16245ADL,118 require external pull-up resistors on direction or enable pins?

No-direction (1DIR/2DIR) and enable (1OE/2OE) inputs have standard CMOS thresholds and do not include bus hold. However, they exhibit high input impedance (>10¹² Ω), so external pull-ups/downs are only needed if those control signals float during power-up or reset-design practice, not device requirement.
