Texas Instruments TLC59213IPWR

Overview

TLC59213IPWR from Texas Instruments is an 8-bit parallel-input Darlington source driver IC with latch, designed for high-current LED and resistive load switching in printer heads and display matrices. It delivers up to –500 mA per channel, features TTL/CMOS-compatible inputs (V_IL = 0.8 V, V_IH = 2 V), and operates from 4.5 V to 13.2 V supply across –40°C to 85°C.

For engineers reviewing the TLC59213IPWR datasheet, TLC59213IPWR pinout, TLC59213IPWR application, or TLC59213IPWR equivalent, key selection criteria include output saturation voltage (V_CE(sus) = 13.2 V), clock input support up to 1 MHz, integrated clamp diodes for inductive loads, and TSSOP-20 package compatibility with high-density PCB layouts.

Technical Context

The TLC59213IPWR implements eight independent positive-edge-triggered D-type flip-flops, each driving a Darlington transistor with collector tied to V_CC. Input data (D1–D8) is latched on CLK rising edge, while CLR provides asynchronous output disable. The device uses open-collector Darlington outputs with internal clamp diodes to ground for flyback energy dissipation.

It supports simultaneous conduction of multiple outputs with current derating based on duty cycle and number of active channels - e.g., 350 mA per channel at <10% duty cycle in TSSOP package. Timing parameters include 50 ns minimum setup time (t_su) and 50 ns hold time (t_h) for the TLC59213 variant, with propagation delays under 250 ns (t_PLH/t_PHL) at 25°C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Darlington source driver applications.

Compared with TLC59213AIPWR, the TLC59213IPWR offers sufficient timing margin for most 1-MHz applications but lacks the tighter hold specification. Versus ULN2803A, it provides essential latch+clock control and source topology - critical for LED matrix and printer head synchronization - making it non-interchangeable without board-level redesign.

FAQ

What is the maximum continuous output current per channel for TLC59213IPWR?

The TLC59213IPWR supports up to –500 mA peak output current per channel, but continuous current depends on duty cycle and number of simultaneously active outputs. In TSSOP-20 package, it delivers 350 mA per channel at <10% duty cycle and 170 mA at <50% duty cycle across all 8 channels, as specified in the recommended operating conditions table of the SLVS867B datasheet.

Does TLC59213IPWR include internal protection diodes?

Yes, the TLC59213IPWR integrates clamp diodes between each Y-output and GND. These diodes provide flyback protection for inductive loads such as relays and solenoids, eliminating the need for external freewheeling diodes in typical applications.

Can TLC59213IPWR be used with a 3.3-V microcontroller?

Yes - the TLC59213IPWR accepts TTL/CMOS logic inputs with V_IL ≤ 0.8 V and V_IH ≥ 2.0 V, making it compatible with 3.3-V MCUs. However, its V_CC must be supplied at 4.5–13.2 V to ensure proper Darlington driver operation and output current capability.

What is the function of the CLR pin on TLC59213IPWR?

The CLR (Clear) pin on TLC59213IPWR is an active-low asynchronous input that forces all eight Y-outputs to the OFF (high-impedance) state immediately, overriding the CLK and D-input states. This allows rapid, deterministic shutdown of all connected loads without waiting for a clock edge.

Is TLC59213IPWR pin-compatible with TLC59213AIPWR?

Yes, TLC59213IPWR and TLC59213AIPWR share identical pinout, package (TSSOP-20), electrical specifications, and functional behavior. The only difference is the enhanced data hold time (t_h) in the 'A' variant - making them drop-in replacements in most designs, though timing-critical systems should verify hold margin compliance.
