NXP Semiconductors 74LV153DB,118

Overview

74LV153DB,118 from NXP Semiconductors is a low-voltage CMOS dual 4-input multiplexer with independent active-LOW output enables (1E, 2E), common select inputs (S0, S1), and non-inverting outputs. It operates from 1.0 V to 3.6 V, supports TTL input levels at VCC ≥ 2.7 V, and functions across −40 °C to +125 °C - enabling data routing in battery-powered logic systems and industrial control I/O expansion.

For engineers reviewing the 74LV153DB,118 datasheet, 74LV153DB,118 pinout, 74LV153DB,118 application, or 74LV153DB,118 equivalent, this device serves as a pin- and function-compatible upgrade to 74HC153/74HCT153 in low-voltage designs requiring dual-channel signal selection, bus multiplexing, or irregular logic synthesis with guaranteed timing at 3.3 V.

Technical Context

The 74LV153DB,118 implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate enable inputs (1E, 2E) for strobing each output (1Y, 2Y) independently. Its logic equations explicitly define output behavior as 1Y = 1E × Σ(1In × S1 × S0) and 2Y = 2E × Σ(2In × S1 × S0), confirming true dual-pole, 4-position switch functionality.

It uses Si-gate CMOS technology with ESD protection exceeding 2000 V HBM and 200 V MM, and delivers propagation delays as low as 10 ns (nE → nY) and 14 ns (1In → 1Y) at VCC = 3.3 V with CL = 15 pF - optimized for high-speed digital control paths where deterministic latency and rail-to-rail output swing are required.

FAQ

What is the maximum clock frequency supported by the 74LV153DB,118?

The 74LV153DB,118 does not operate on a clock signal - it is a combinatorial multiplexer with propagation delay as the key timing parameter. At VCC = 3.3 V and CL = 15 pF, its worst-case 1In → 1Y delay is 33 ns, supporting input switching frequencies up to approximately 15 MHz in static-select configurations. For dynamic select changes, system-level setup/hold timing must be verified against the 10 ns nE → nY delay.

Does the 74LV153DB,118 support 5 V tolerant inputs?

No, the 74LV153DB,118 is not 5 V tolerant. Its absolute maximum input voltage is VCC + 0.5 V. However, it accepts TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V) when VCC is between 2.7 V and 3.6 V - enabling safe interface with 5 V TTL outputs without external clamping, provided VCC remains within specification.

Can the 74LV153DB,118 be used to cascade multiplexers for larger data routing?

Yes, the 74LV153DB,118 supports cascading via its individual output enables (1E, 2E). By connecting 1Y or 2Y to another multiplexer's data input and controlling 1E/2E as a higher-order select line, designers can build 8:1 or 16:1 structures. The datasheet explicitly states "Enable line provided for cascading (n lines to 1 line)" - confirming this architecture is validated.

What is the quiescent supply current of the 74LV153DB,118 at 3.3 V?

At VCC = 3.6 V and Tamb = 25 °C, the typical supply current (ICC) of the 74LV153DB,118 is 20 µA, with a maximum of 160 µA over the full −40 °C to +125 °C range. This ultra-low ICC enables use in always-on monitoring circuits where standby power must remain below 1 mW.

Is the 74LV153DB,118 pin-compatible with the 74HC153?

Yes, the 74LV153DB,118 is explicitly stated as pin and function compatible with 74HC153 and 74HCT153. All 16 pins match in position and logical role, including VCC (16), GND (8), S0 (14), S1 (2), 1E (1), 2E (15), 1Y (7), 2Y (9), and all eight data inputs - enabling direct replacement in existing HC/HCT designs when migrating to lower supply voltages.
