NXP Semiconductors N74F153N,602

Overview

N74F153N,602 from Philips Semiconductors is a dual 4-line to 1-line TTL multiplexer in 16-pin plastic DIP (SOT38-4) packaging, featuring non-inverting outputs, separate active-Low enables (Ea, Eb), and common select inputs (S0, S1). It selects two independent data bits from four input sources per section and drives logic-level outputs with 7.0 ns typical propagation delay and 12 mA typical supply current at 5 V, used in digital address/data routing and bus arbitration circuits.

For engineers reviewing the N74F153N,602 datasheet, N74F153N,602 pinout, N74F153N,602 application, or N74F153N,602 equivalent, key selection considerations include enable-controlled output gating, common-select architecture for synchronized channel selection, TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), and operation across 0°C to +70°C commercial temperature range.

Technical Context

The N74F153N,602 implements two independent 4:1 multiplexers sharing S0/S1 select lines but with dedicated active-Low enables (Ea, Eb), enabling selective channel activation without inter-channel timing coupling. Each section drives a non-inverting output (Ya, Yb) that is forced Low when its respective enable is High.

Its logic behavior follows a standard truth table where output Yn equals In selected by S0/S1 when En is Low; all outputs are Low when En is High. Propagation delays are asymmetric: 7.0 ns max (In→Yn), 12.0 ns max (Sn→Yn), and 8.0 ns max (En→Yn) under 5 V ±10%, CL = 50 pF conditions.

FAQ

What is the operating voltage range for N74F153N,602?

The N74F153N,602 operates over a supply voltage range of 4.5 V to 5.5 V, with nominal performance specified at 5.0 V. This range ensures compatibility with standard 5 V TTL power rails and accommodates typical ±10% tolerance in commercial power supplies. Operation outside this range may impair functionality or reliability, as defined in the Absolute Maximum Ratings table.

Does N74F153N,602 support 3.3 V logic inputs?

No, N74F153N,602 does not reliably accept 3.3 V logic inputs. Its input thresholds require VIH ≥ 2.0 V and VIL ≤ 0.8 V under 5 V operation, and it lacks 3.3 V tolerance. Driving it from 3.3 V logic may result in marginal or incorrect switching due to insufficient high-level margin. Level-shifting circuitry is required for interfacing with 3.3 V systems.

How are the enables (Ea, Eb) used in N74F153N,602?

In N74F153N,602, Ea and Eb are active-Low enables controlling Ya and Yb independently. When Ea = Low, Ya reflects the selected input (I0a–I3a) per S0/S1; when Ea = High, Ya is forced Low regardless of inputs or selects. The same applies to Eb/Yb. This allows time-multiplexed or conditional output activation without altering select lines.

What is the maximum output sink current for N74F153N,602?

The N74F153N,602 supports a maximum Low-level output current (IOL) of 20 mA per output (Ya or Yb), as specified under recommended operating conditions. This enables direct driving of multiple TTL inputs or LEDs with appropriate current-limiting resistors. Exceeding 20 mA risks exceeding absolute maximum ratings and may cause output voltage degradation or device damage.

Is N74F153N,602 pin-compatible with the 74F253?

No, N74F153N,602 is not pin-compatible with the 74F253. While both are dual 4:1 multiplexers, the 74F253 features 3-State outputs and different pin assignments (e.g., OE instead of individual Ea/Eb, and Y outputs with tri-state control). The N74F153N,602 has open-collector–compatible non-inverting outputs and dedicated Ea/Eb pins - substitution would require PCB layout changes and logic redesign.
