74ALVCH16501 - 18-bit universal bus transceiver

Description

The 74ALVCH16501 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs.

Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CPAB and CPBA) inputs.

Features

  • Wide supply voltage range from 1.2 V to 3.6 V.
  • CMOS low power dissipation.
  • Direct interface with TTL levels.
  • Current drive ±24 mA at VCC = 3.0 V.
  • Universal bus transceiver with D-type latches and D-type flip-flops capable of operating in transparent, latched or clocked mode.
  • Bus hold on all data inputs.
  • Output drive capability 50 Ω transmission lines at 85 °C.
  • 3-state non-inverting outputs for bus-oriented.

74ALVCH16501 18-bit universal bus transceiver; 3-state Rev. 7 — 24 November 2021 Product data sheet 1. General description The 74ALVCH16501 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs. Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CPAB and CPBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is HIGH. When LEAB is LOW, the A data is latched if CPAB is held at a HIGH or LOW logic level. If LEAB is LOW, the A-bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CPAB. When OEAB is HIGH, the outputs are active. When OEAB is LOW, the outputs are in the high-impedance state.
