Nexperia USA Inc. 74LVT162240ADL,112

Overview

74LVT162240ADL,112 from Nexperia is a 3.3 V 16-bit inverting 3-state buffer/driver with integrated 30 Ω series termination on all outputs, designed for high-noise-margin bus driving in memory address, clock distribution, and data bus applications. It features four independent output-enable inputs (1OE–4OE), ±12 mA drive strength, TTL-compatible I/O, and bus-hold inputs eliminating external pull-ups.

For engineers reviewing the 74LVT162240ADL,112 datasheet, 74LVT162240ADL,112 pinout, 74LVT162240ADL,112 application, or 74LVT162240ADL,112 equivalent, this device serves as a noise-suppressed, 48-pin TSSOP bus interface IC with guaranteed -40 °C to +85 °C operation, 2.6 ns typical propagation delay, and 30 Ω on-die termination enabling clean signal integrity without discrete resistors.

Technical Context

The 74LVT162240ADL,112 implements a BiCMOS architecture optimized for 3.3 V VCC operation while maintaining full 5 V input tolerance and TTL-level compatibility. Its four independent 4-bit output groups are each controlled by dedicated active-low OE pins, enabling granular bus partitioning and power-aware enable sequencing.

Each output integrates matched 30 Ω series resistance in both pull-up and pull-down paths-verified per Fig. 3 schematic-reducing ringing and overshoot on transmission lines without requiring external termination. Bus-hold circuitry on all 16 inputs maintains valid logic states during floating conditions, supporting live insertion and reducing system-level BOM count.

FAQ

Is the 74LVT162240ADL,112 pin-compatible with older 74LVT162240 variants?

Yes-the 74LVT162240ADL,112 uses the same SOT362-1 (TSSOP48) footprint and pinout as the original 74LVT162240A, including identical VCC, GND, OE, input, and output assignments. Revision 6 documentation confirms mechanical and functional equivalence with no layout changes required for drop-in replacement.

Can the 30 Ω internal termination be bypassed or disabled?

No-the 30 Ω series resistance is hard-wired within each output stage and cannot be disabled or configured. It is always active when the output is enabled (OE low) and presents no additional impedance in 3-state (high-Z) mode. This fixed design ensures consistent signal integrity without user configuration overhead.

What is the maximum sustained output current per pin during continuous operation?

The absolute maximum DC output current per pin is ±128 mA (LOW) and ±64 mA (HIGH) per Table 4, but the recommended operating condition limits sustained current to ±12 mA. Exceeding ±12 mA continuously risks exceeding junction temperature limits and violating SOA-designs must ensure thermal dissipation or duty-cycle derating if peak currents approach limiting values.

Does the bus-hold feature affect timing or power consumption?

Bus-hold circuitry draws ±75 μA to ±135 μA per input (Table 6), adding negligible static current (<2.2 μA total for all 16 inputs). It introduces no measurable propagation delay penalty and operates transparently-holding inputs at valid logic levels only when voltage falls within the 0.8 V to 2.0 V indeterminate zone, with no impact on normal switching behavior.
