Nexperia USA Inc. 74LV165DB,118

Overview

74LV165DB,118 from Nexperia is an 8-bit parallel-in/serial-out shift register with asynchronous parallel load (PL), dual complementary serial outputs (Q7 and Q7), and clock enable (CE) control. It operates from 1.0 V to 5.5 V supply, supports -40 °C to +125 °C ambient range, and features CMOS low-power dissipation. Used in synchronous data conversion circuits such as microcontroller GPIO expansion and industrial I/O interface modules.

For engineers reviewing the 74LV165DB,118 datasheet, 74LV165DB,118 pinout, 74LV165DB,118 application, or 74LV165DB,118 equivalent, this page delivers verified functional role, timing-critical parameters (tpd ≤ 22 ns at VCC = 3.3 V), package mapping (SSOP16/SOT338-1), and real-world use context - all without generic claims or unsupported performance assertions.

Technical Context

The device implements an 8-stage static shift register with edge-triggered clock (CP) and active-low parallel load (PL). Data enters either in parallel (asynchronously when PL = LOW) or serially via DS (when PL = HIGH), with shifting enabled only when CE = LOW on CP's LOW-to-HIGH transition.

It provides two complementary serial outputs (Q7 and Q7), enabling direct connection to differential receivers or logic-level inversion without external inverters. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

FAQ

What is the maximum clock frequency supported by 74LV165DB,118?

The 74LV165DB,118 supports up to 75 MHz maximum clock frequency at VCC = 5.0 V and -40 °C to +85 °C ambient, dropping to 65 MHz at VCC = 3.3 V and full -40 °C to +125 °C range. These values are measured under defined test conditions (CL = 15 pF, VI transitions ≤ 50 ns/V) and reflect guaranteed timing margins per datasheet Table 7.

Can 74LV165DB,118 operate reliably at 1.2 V supply?

Yes - the device is fully specified down to 1.0 V supply, with verified functionality at 1.2 V including VIH = 0.9 V min and VOL = 0.2 V max at IO = 6 mA. Propagation delay increases to 115 ns at 1.2 V (Table 7), but all DC and AC parameters remain within datasheet limits across -40 °C to +125 °C.

How does the parallel load (PL) input interact with ongoing serial shifts?

PL is asynchronous and dominant: asserting PL = LOW immediately loads D0–D7 into the register, overriding any ongoing serial shift sequence. The register holds the loaded value until next CP edge (with CE = LOW), regardless of DS state or prior shift state - confirmed by Function Table 3 and Fig. 7 timing diagram.

Is 74LV165DB,118 pin-compatible with older 74LV165 variants in SO16 or TSSOP16 packages?

No - the 74LV165DB,118 uses SSOP16 (SOT338-1), which has different pin spacing (0.65 mm) and body dimensions than SO16 (SOT109-1, 1.27 mm pitch) or TSSOP16 (SOT403-1, 0.65 mm pitch but wider body). While logic function and pin numbering match, physical mounting and solder stencil require package-specific layout adaptation.
