HT6508ARZ

HTCSEMI · RS-485 / RS-422 ICs · SOP-8

HT6508ARZ from HTCSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RO output Receiver Output. Logic-level output of the differential receiver comparing A and B. High when A-B > +0.2V, low when A-B < -0.2V; fail-safe high when inputs are open. High-impedance when RE is high. VOH ≥ 2.5V at Io = -1.5mA; VOL ≤ 0.4V at Io = 2.5mA.
2 /RE input Receiver Output Enable, active low. Drive low to enable the receiver output RO; drive high to place RO in high-impedance state. TTL/CMOS compatible input (VIH ≥ 2.0V, VIL ≤ 0.8V).
3 DE input Driver Output Enable, active high. Drive high to enable driver outputs A and B; drive low to place driver outputs in high-impedance state. TTL/CMOS compatible input (VIH ≥ 2.0V, VIL ≤ 0.8V).
4 DI input Driver Input. Logic-level input to the differential driver. When DE=1: DI=0 forces A=0/B=1, DI=1 forces A=1/B=0. TTL/CMOS compatible (VIH ≥ 2.0V, VIL ≤ 0.8V).
5 GND power_in Ground reference. All voltages are referenced to this pin.
6 A bidirectional Non-inverting Driver Output / Non-inverting Receiver Input (RS-485/RS-422 bus line A). Withstands -7V to +12V common-mode; input resistance ≥12kΩ. Short-circuit current limited to 250mA over -7V ≤ Vo ≤ 12V; protected by thermal shutdown.
7 B bidirectional Inverting Driver Output / Inverting Receiver Input (RS-485/RS-422 bus line B). Withstands -7V to +12V common-mode; input resistance ≥12kΩ. Short-circuit current limited to 250mA over -7V ≤ Vo ≤ 12V; protected by thermal shutdown.
8 VCC power_in Supply voltage input. Single 3.3V ±0.3V supply. No-load quiescent supply current typically 120µA (RE=0V, DE=0V). Absolute maximum 7V.
